Parallel
Isaiah 29:13
Jewish Publication Society 1917 · Berean Standard Bible
And the Lord said: Forasmuch as this people draw near, and with their mouth and with their lips do honour Me, But have removed their heart far from Me, And their fear of Me is a commandment of men learned by rote;
Therefore the Lord said: “These people draw near to Me with their mouths and honor Me with their lips, but their hearts are far from Me. Their worship of Me is but rules taught by men (note: Hebrew; LXX They worship Me in vain; they teach as doctrine the precepts of men. Cited in Matthew 15:8–9 and Mark 7:6–7).
