I became also a reproach unto them - They reproached or reviled me as a bad man. Compare the notes at Psalms 22:6. The plural here - “unto them” - shows that there were more than one to whom the psalm had reference, though one of them was so prominent that a considerable part of the psalm might properly be spoken of him alone.
When they looked upon me, they shaked their heads - In contempt. See Psalms 22:7. Compare Matthew 27:39.
