to contend with someone: to set yourself against another and hold out rather than give way
This verb turns up in only two places in the Bible, and both are about the same night. In Genesis a stranger wrestles Jacob until daybreak, then tells him his name will no longer be Jacob but Israel, "because you have contended with God and with men, and you have prevailed." Hosea repeats the line centuries later when he retells the story. Everything we know about the word comes from that one episode and the prophet's echo of it.
Two neighboring words help fix what it does and does not say. The physical grappling in Genesis is carried by a different verb (אָבַק), used three verses earlier, so "wrestle" is the picture of the scene rather than the meaning of this word. And in both verses the winning is stated separately, by a second verb meaning "and he prevailed" (יָכֹל). What is left for this word is the contending itself: standing against another and not backing down.
The oldest translators heard it differently than modern ones do. The ancient Greek and Latin versions both render it "you have been strong," and the old Aramaic version goes further still, "you have become great before the Lord." They pulled the word toward the common verb for ruling and acting as a prince (שָׂרַר), which in Hebrew differs from it by a single letter. Modern dictionaries have moved the other way, settling on "strive, contend, struggle." Both readings survive in English Bibles, in the King James "as a prince hast thou power with God" against the modern "you have striven with God."
The word carries an enormous load for its size, because a nation's name hangs on it. Genesis ties the name Israel (יִשְׂרָאֵל) to this verb, but most scholars think the name is older than the story, and that in names built this way it is God who does the verb, not the person. On that reading the name originally said something like "God rules" or "God persists," and the line in Genesis is a deliberate play on words rather than a word history.
Disputed
Whether the core sense of the verb is contending and striving, or being strong and prevailing.
- majorityThe verb means "strive, contend, struggle," the standard gloss of the modern lexica.; BDB, s.v. שָׂרָה I (p. 975); HALOT, s.v. שׂרה; DCH, ed. D. J. A. Clines, vol. 8 (2011), s.v. שׂרה
- minorityThe center of gravity is "be strong, persist, prevail," close in sense to שׂרר "to rule"; every ancient version read the verb this way.; E. A. Speiser, Genesis, Anchor Bible 1 (1964), 254; Nahum M. Sarna, Genesis, JPS Torah Commentary (1989), 227-228
