'Ashamed' in the Bible

for I was ashamed to ask from the king a force and horsemen to help us because of the enemy in the way, for we spake to the king, saying, 'The hand of our God is upon all seeking Him for good, and His strength and His wrath is upon all forsaking Him.'

and say, 'O my God, I have been ashamed, and have blushed to lift up, O my God, my face unto Thee, for our iniquities have increased over the head, and our guilt hath become great unto the heavens.
