What does Psalm 22:7 mean?

The treatment being endured here is not merely painful, it is humiliating. David describes the insulting treatment he received from his foes when he felt abandoned by God (Psalm 22:1–2, 6). This serves as insight into David's angst, as well as a prediction about the suffering of the Promised One (Matthew 27:46; Psalm 22:1).

These words describe precisely what Jesus would experience at the hands of those who despised Him. They would mock Him and part their lips to form a vicious grin (Psalm 35:21). They would also shake their heads to indicate His situation was hopeless. Matthew 27:39–42 reports the insults Jesus received when He hung on the cross. Those who passed by wagged their heads and ridiculed His claim that He would destroy the temple and rebuild it in three days. They impudently called upon Him to support His claim to be the Son of God by coming down from the cross. The chief priests, scribes, and elders also mocked Him. They said He saved others but could not save Himself. Like the passersby, they challenged Him to prove His messianic claim by coming down from the cross.
