The Hebrew noun gemul refers to a recompense, reward, or the result of one's deeds — the natural consequence of how a person has acted toward others. It can be used in both a positive sense (benefit, reward) and a negative sense (retribution, punishment for evil).
Gemul captures the biblical principle of sowing and reaping. God is portrayed as the one who renders gemul according to deeds. In the Psalms, the righteous trust that YHWH will repay the wicked and reward the faithful — not as vengeance but as the proper order of justice.
Theologically, gemul teaches that human actions carry weight before God. The New Testament echoes this in Galatians 6:7 — 'A man reaps what he sows' — and in God's ultimate judgment.
