'Prove' in the Bible

Now be courageous and prove to be valiant warriors, for your lord Saul is dead. The people of Judah have anointed me as king over them."

Now, O sovereign Lord, you are the true God! May your words prove to be true! You have made this good promise to your servant!

He said, "If the Arameans prove too strong for me, then you are to help me. If the Ammonites prove too strong for you, then I will come help you.

Be strong! We must prove ourselves strong for our people and for the cities of our God. May the Lord’s will be done.”

With the faithfulYou prove Yourself faithful;with the blameless manYou prove Yourself blameless;

with the pureYou prove Yourself pure,but with the crookedYou prove Yourself shrewd.
