'Dealt' in the Bible

But Abram said to Sarai, “Look, your maid is entirely in your hands and subject to your authority; do as you please with her.” So Sarai treated her harshly and humiliated her, and Hagar fled from her.

so now, swear to me here by God that you will not deal unfairly with me [by breaking any agreements we have] or with my son or with my descendants, but as I have treated you with kindness, you shall do the same to me and to the land in which you have sojourned (temporarily lived).”

Please accept my blessing (gift) which has been brought to you, for God has dealt graciously with me and I have everything [that I could possibly want].” So Jacob kept urging him and Esau accepted it.
