'Embarrassed' in the Bible

I was embarrassed to request soldiers and horsemen from the king to protect us from the enemy along the way, because we had said to the king, "The good hand of our God is on everyone who is seeking him, but his great anger is against everyone who forsakes him."

And I said:My God, I am ashamed and embarrassed to lift my face toward You, my God, because our iniquities are higher than our heads and our guilt is as high as the heavens.
