'Dealt' in the Bible

Abram answered Sarai, "Look, your servant is under your control, so do to her as you wish." So Sarai dealt so harshly with Hagar that she ran away from Sarai.

"Your servant has found favor in your sight, and you have shown me your gracious love in how you have dealt with me by keeping me alive. I cannot escape to the hills, because I'm afraid the disaster will overtake me, and I'll die.

Therefore swear an oath here by God that you won't deal falsely with me, my sons, or my descendants. Just as I've dealt graciously with you, won't you do so with me and with the land in which you live as a foreigner?"
