In the statement, “Ye do err, not knowing the scripture, nor the power of God” (Matthew 22:29), Jesus is addressing the mistakes made by the Sadducees in their understanding of the resurrection. They were questioning Jesus about a hypothetical scenario involving the resurrection and marriage, and Jesus points out that they were wrong because they lacked understanding of both the Scriptures and the power of God.

This statement implies that when people don’t know the Scriptures or the power of God, they may fail to properly understand or interpret spiritual truths. Jesus is calling attention to the fact that a correct understanding of God’s Word and His divine power is important for making accurate spiritual judgments.
