Matthew 23:25 records the same 'clean outside but inside full of greed' saying, confirming it as a core Jesus teaching against hypocrisy.

In Matthew 12:33-35, Jesus teaches that the heart determines speech and actions — the same inside-out principle underlying the cup metaphor.

In 2 Chronicles 31:21, Hezekiah's seeking God with all his heart directly opposes the Pharisees' divided hearts.

In 2 Chronicles 31:20, Hezekiah's wholehearted faithfulness contrasts with the Pharisees' outward show — a model of integrated devotion.

In Matthew 5:20, Jesus says righteousness must surpass the Pharisees' external compliance—directly echoing the inward vs outward contrast here.

Mark 7:4 describes the very practice of washing cups and dishes that Jesus condemns here—external ritual without internal purity.

In Mark 7:6, Jesus quotes Isaiah about honoring God outwardly while hearts are far away—the same hypocrisy of clean outside, corrupt inside.
