In Matthew 7:5, Jesus also calls out the hypocrite who judges others while ignoring his own sin — same term and theme.

In Matthew 23:23-29, Jesus expands on the same hypocrisy of Pharisees — meticulous tithing yet neglecting justice and mercy.

Matthew 6:2 warns against hypocrites who give to be seen — same term and critique of external religiosity.

In Matthew 16:3, Jesus similarly rebukes religious leaders for failing to discern spiritual signs, paralleling the hypocrisy condemned in Matthew 15:7.

Mark 7:6 is the parallel account of this same event, quoting Isaiah 29:13 against the Pharisees.

Isaiah 29:13 is the exact prophecy Jesus quotes — people honor God with lips but hearts are far away.

In Luke 13:15, Jesus uses the same 'hypocrites' label for those prioritizing rules over compassion, mirroring the rebuke in Matthew 15:7.

In 1 Peter 2:1, believers are commanded to rid themselves of hypocrisy, directly connecting to the sin Jesus condemns in Matthew 15:7.

In Luke 18:12, the Pharisee's boastful prayer exemplifies the outward display without heart that Jesus condemns in Matthew 15:7.

In John 4:23, Jesus describes true worship in spirit and truth, contrasting with the lip-service hypocrisy condemned in Matthew 15:7.

Isaiah 58:2 describes people who seek God outwardly but lack true devotion — a parallel to the lip-service condemned in Isaiah 29:13.

Acts 28:25-27 quotes Isaiah 6:9-10 about spiritual dullness — another Isaiah prophecy explaining unbelief, similar to Jesus' use here.
