Bakar (בָּכַר) means to bring forth the firstborn or to bear first fruit. The verb is the root behind bekor (H1060, firstborn) and bikkurim (H1061, first fruits). It encapsulates the Hebrew theology of priority — the first of everything belongs to God, sanctifying the whole.
The firstborn principle runs throughout Scripture: the firstborn son received the double inheritance, the birthright, and the blessing. God claimed all firstborn of Israel (Exodus 13:2) as His own — redeemable by price, pointing forward to Christ, the "firstborn over all creation" (Colossians 1:15). The feast of firstfruits (bikkurim) required that the initial yield of the harvest be offered to God before any was consumed, an act of trust that more would follow. Giving God the first is the antithesis of Cain's offering — the difference between reluctant leftovers and wholehearted priority.
The noun family: bekor (H1060, firstborn son), bekorah (H1062, birthright), bikkurim (H1061, first fruits). Esau's sale of his bekorah for stew (Genesis 25) is tragedy because he traded eternal priority for momentary appetite. Christ as "firstborn from among the dead" (Colossians 1:18) signals that the resurrection inaugurates a new creation — He is its first yield, guaranteeing the full harvest to come.
