'Dealt' in the Bible

I will sing to the LORD, for he has dealt bountifully with me. To the Director: A Davidic Psalm.

All this came upon us, yet we did not forsake you, and we have not dealt falsely with your covenant;

LORD, you have dealt well with your servant, according to your word.

He has not dealt with any other nation like this; they never knew his decrees. Hallelujah!
