1. to formally approve or permit something
2. to impose a penalty on or punish someone.

The two meanings can be contradictory. An auto-antonym is a word that can have contradictory meanings.

Next, the Hebrew word חֶסֶד (hesed) occurred 248 times in 241 verses, and in 28 of the 39 OT books. It was an important biblical theme.

The word first appeared in Genesis 19:

19 Now behold, your servant has found favor in your sight, and you have magnified your lovingkindness (hesed), which you have shown me by saving my life; but I cannot escape to the mountains, for the disaster will overtake me and I will die.

But in Leviticus 20:17, the meaning was to be opposite:

If there is a man who takes his sister, his father's daughter or his mother's daughter, so that he sees her nakedness and she sees his nakedness, it is a disgrace (hesed); and they shall be cut off in the sight of the sons of their people.
