He spoke of this in his song of redemption. In Revelations this song is called the song of Moses and the Lamb. The Rock is Christ. This is likely a prophecy that reaches to the time of Christ. But the defect issue has to do with the unregenerated person.
All sinners carry a spiritual defect.
This defect can only be removed by the blood of the Lamb in an act of regeneration. Peter quoted from them on the day of Pentecost, when he preached Jesus as the Christ of God. The redemptive program is not an issue of anti-semitiism. The early Church was exclusively Jewish at the beginning. The perverse generation would apply to all who made themselves the enemy of Christ.
