'Find' in the Bible

I said to them, “We according to our ability have redeemed our Jewish brothers who were sold to the nations; now would you even sell your brothers that they may be sold to us?” Then they were silent and could not find a word to say.

“You found his heart faithful before You,And made a covenant with himTo give him the land of the Canaanite,Of the Hittite and the Amorite,Of the Perizzite, the Jebusite and the Girgashite—To give it to his descendants.And You have fulfilled Your promise,For You are righteous.
