He suffered no man to do them wrong - He protected them as they wandered from place to place, and as they were exposed to dangers. See the history of Abraham, Isaac, and Jacob, in their wanderings, as it is recorded in the book of Genesis.
Yea, he reproved kings for their sakes - That he might protect them; that he might keep them from danger and from sin. See the case of Pharaoh in the time of Abraham, Genesis 12:17-20, and the case of Abimelech, Genesis 20:3, Genesis 20:6.
