Emulation
The older English word emulation carries two faces in scripture. One is the sinful face — the rivalry that envies a neighbor's portion and resents another's gift. The other is the holy face — the stir-up of zeal that one believer's earnestness produces in another, the pull toward love and good works. The same verb in Romans 11:11, "to provoke them to jealousy," names a redemptive purpose; the same impulse in Genesis 30 tears a household apart. The biblical material sets the two side by side and asks the reader to know which one is at work.
Yahweh's Jealousy as the Backdrop
Before any human jealousy is forbidden, divine jealousy is named as part of who God is. The second commandment grounds the prohibition of idols in this self-disclosure: "I Yahweh your God am a jealous God, visiting the iniquity of the fathers on the sons" (Ex 20:5). The point is repeated in the Sinai renewal — "For Yahweh, whose name is Jealous, is a jealous God" (Ex 34:14) — and sharpened in Deuteronomy: "For Yahweh your God is a devouring fire, a jealous God" (Deut 4:24; cf. Deut 29:20). Joshua presses the same warning on the covenant generation: "he is a holy God; he is a jealous God; he will not forgive your⁺ transgression nor your⁺ sins" (Josh 24:19).
Israel's later history is read through this lens. Judah "did that which was evil in the sight of Yahweh, and they provoked him to jealousy with their sins" (1Ki 14:22), and Paul presses the same point on the Corinthian table: "Or do we provoke the Lord to jealousy? Are we stronger than he?" (1Co 10:22). Divine jealousy is not the disorder of human envy; it is the proper insistence of a covenant Husband on undivided loyalty.
The Sinful Face: Envy and Rivalry
Human jealousy in its disordered form runs through the patriarchal narratives. Cain is the first case: "but to Cain and to his offering he did not have respect. And Cain was very angry, and his countenance fell" (Gen 4:5). Isaac's prosperity provokes his neighbors — "he had possessions of flocks ... and the Philistines envied him" (Gen 26:14). The pattern intensifies in Joseph's brothers, where envy moves to hatred: "his brothers saw that their father loved him more than all his brothers; and they hated him, and could not speak peacefully to him" (Gen 37:4); "his brothers envied him; but his father kept the saying in mind" (Gen 37:11).
Two illustrations belong here. The first is Esau's marriages. When Esau "saw that the daughters of Canaan didn't please Isaac his father ... [he] went to Ishmael, and took, besides the wives that he had, Mahalath the daughter of Ishmael" (Gen 28:8-9). Watching Jacob obey the parental charge, Esau attempts to match the gesture by a marriage that he hopes will please — not from conviction, but from rivalry with the brother he has already lost the blessing to.
The second is Jacob's own household, where the rivalry between Rachel and Leah defines the births of the tribes. "When Rachel saw that she did not bear for Jacob, Rachel envied her sister; and she said to Jacob, Give me sons, otherwise I will die" (Gen 30:1). Each son is named into the contest: Naphtali — "With mighty wrestlings I have wrestled with my sister, and have prevailed" (Gen 30:8); the mandrake bargain — "Is it a small matter that you have taken away my husband? And would you take away my son's mandrakes also?" (Gen 30:15). The whole pericope shows what emulation in its sinful sense produces: a domestic economy of grievance, surrogate wives, named slights, and even the womb itself read as a scoreboard until "God remembered Rachel" (Gen 30:22).
The same pattern recurs across the canon. Korah and his company resent Moses and Aaron — "You⁺ take too much on yourselves" (Num 16:3). The Ephraimites resent Gideon for going to war without them (Judg 8:1). Saul, hearing the women's song that praises David's ten thousands against his thousands, reduces the whole future to threat: "and what can he have more but the kingdom?" (1Sam 18:8). The men of Israel and the men of Judah quarrel over which tribe brought the king back across the Jordan (2Sam 19:41). The presidents and satraps under Darius search Daniel for any fault and find none — the faultlessness itself feeds the envy (Dan 6:4). Haman cannot enjoy his honors "so long as I see Mordecai the Jew sitting at the king's gate" (Esth 5:13). The elder brother in the parable refuses to come in to the feast (Luke 15:28).
The wisdom literature names the affect for what it is. "Jealousy is the rage of a [noble] man; And he will not spare in the day of vengeance" (Prov 6:34). "A tranquil heart is the life of the flesh; But envy is the rottenness of the bones" (Prov 14:30). The Psalmist confesses, "I was envious at the arrogant, When I saw the prosperity of the wicked" (Ps 73:3). Ben Sira presses the same: "Envy and anger shorten days, And anxiety makes gray before the time" (Sir 30:24); "[There is but] anger and jealousy, anxiety and fear, Terror of death, strife and contention" (Sir 40:5). The picture is of a corrosive appetite that eats its host.
Wisdom's Counsel: Do Not Envy
Set against the examples is the steady refrain of the wisdom literature and the apostolic exhortation. "Don't fret yourself because of evildoers, Neither be envious against those who work unrighteousness" (Ps 37:1). "Don't envy the man of violence" (Prov 3:31); "Don't let your heart envy sinners; But [be] in the fear of Yahweh all the day long" (Prov 23:17); "Don't be envious against evil men; Neither desire to be with them" (Prov 24:1). Ben Sira adds the domestic side — "Do not be jealous of the wife of your bosom" (Sir 9:1) — and the general counsel against envying either the wicked or the prosperous proud (Sir 9:11; Sir 9:12).
The apostles carry the same prohibition into the new covenant. Paul lists jealousy with the night-works that the Christian must put off: "Let us walk becomingly, as in the day; not in reveling and drunkenness, not in promiscuity and sexual depravity, not in strife and jealousy" (Rom 13:13). Love is defined against it: "Love does not envy" (1Cor 13:4). And to the Galatians the warning is explicit, using the very word the older English versions rendered "emulations": "Let us not become conceited, provoking one another, envying one another" (Gal 5:26). James names the inward source — "if you⁺ have bitter jealousy and faction in your⁺ heart, don't glory and don't lie against the truth" (Jas 3:14).
The Holy Face: Provoking to Love and Good Works
The same vocabulary turns positive when the object turns. The general scriptures grouped under EMULATION are not about suppressing zeal but redirecting it. Israel's stumbling, Paul argues, has a redemptive purpose — "by their fall salvation [has come] to the Gentiles, to provoke them to jealousy" (Rom 11:11). And the apostle accepts that provocation as part of his own calling: "if by any means I may provoke to jealousy [those who are] my flesh, and may save some of them" (Rom 11:14). What the world calls rivalry, the gospel turns into a longing not to be left behind in grace.
Paul's collection for the saints in Jerusalem trades on this redirected emulation in both directions at once. He sets the Macedonian churches before the Corinthians as a goad: "we make known to you⁺ the grace of God which has been given in the churches of Macedonia; how that in much proof of affliction the abundance of their joy and their deep poverty abounded to the riches of their liberality" (2Cor 8:1-2). The aim is not commandment but emulation — "I don't speak by way of commandment, but as proving through the earnestness of others the sincerity also of your⁺ love" (2Cor 8:8). And the same circuit runs back the other way: the Achaian zeal already provokes the Macedonians. "I know your⁺ readiness, of which I glory on your⁺ behalf to them of Macedonia, that Achaia has been prepared for a year past; and your⁺ zeal has stirred up very many of them" (2Cor 9:2).
The summary statement is in Hebrews. "Let us consider one another to provoke to love and good works" (Heb 10:24). The verb is the same family that appears in the warning passages; the difference is the object. Believers are to study one another for the precise purpose of provoking — not envy, not strife, but love.
Two Faces, One Heart
The biblical material does not pretend the two faces of emulation are easily separable. The apostle who urges the Corinthians to provoke one another to love also writes that love itself "does not envy." The Father whose name is Jealous gives Israel as a covenant people who in turn must not "provoke him to jealousy with their sins." The line between holy zeal and sinful rivalry is the line between glorifying another's grace and resenting it. Jacob's sister-wives kept score; the Macedonian churches gave beyond their power and made the Corinthians want to do the same.
