'Ashamed' in the Bible

For I was ashamed to request troops and horsemen from the king to protect us from the enemy along the way, because we had told the king, “The hand of our God is favorable toward all those who seek Him, but His power and His anger are against all those who abandon (turn away from) Him.”

and I said, “O my God, I am ashamed and embarrassed to lift up my face to You, my God, for our wrongdoings have risen higher than our heads and our guilt has grown to the heavens.
