Mark 7:6
He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
Cross-reference
Isaiah 29:13 is the exact verse Jesus quotes here — a prophetic indictment of hypocritical worship that Jesus applies to the Pharisees.
In Ezekiel 33:31, God says the people hear words but don't act, showing love with mouth while heart goes after gain — echoes the heart-lips gap.
In Titus 1:16, Paul describes those who claim to know God but deny him by their deeds — a direct parallel to honoring with lips but heart far away.
In 2 Timothy 3:5, Paul warns of people with a form of godliness but denying its power — matching the lips vs. heart disconnect Jesus condemns.
In John 8:55, Jesus says they have not known God despite claiming to — the heart is far from Him.
Matthew 15:7-9 records the same quotation of Isaiah 29:13 in a parallel account of Jesus rebuking the Pharisees' hypocrisy.
Matthew 23:13 pronounces woe on hypocritical Pharisees, matching Jesus' charge of hypocrisy here when quoting Isaiah.
In Luke 11:39-44, Jesus similarly condemns Pharisees for outward purity while inside full of greed and wickedness — the same hypocrisy.
In John 5:42, Jesus states the Jews have no love for God — the very heart-far-from-me issue from Mark 7:6.
In John 8:54, Jesus notes they say God is their God but don't honor Him — lip service without true reverence.
In John 8:42, Jesus says if God were their Father they would love Him — revealing their heart is far.
In Jeremiah 12:2, God says the people are near in mouth but far from heart — an almost identical OT echo of the hypocrisy Jesus quotes.
In Matthew 15:3, Jesus directly questions why people break God's command for tradition — the same confrontation of outward piety overriding God's law.
In Matthew 6:2, Jesus condemns giving to the needy for public praise — another example of outward display without true devotion to God.
In John 8:41, the Jews claim God as Father, but their actions contradict — a form of honoring with lips only.
In Hosea 8:2, Israel cries 'My God, we know you' yet rejects good — lip service without true devotion.
In James 2:14-17, faith without works is dead — a related theme of outward profession lacking inward reality, though focused on action rather than heart.
