Isaiah 29:13

draw near(i.e. worship) me with their mouth, and with their lips do honour me A.V. is here unquestionably right against R.V., which slavishly follows the Hebrew accentuation, rendering, "draw nigh, and with their mouth and with their lips do honour me." with their mouth … their lips uttering the prescribed liturgical formulæ.

have removed their heart far from me The heart is the organ of intelligence and moral obedience and inclination (cf. Proverbs 23:26).

their fear towards me R.V. their fear of me, i.e. their piety, religion.

is taught by the precept of men Better as R.V.: is (or, has become) a commandment of men which hath been taught; a human ordinance learned by rote (cf. Matthew 15:1-9). This pregnant criticism expresses with epigrammatic force the fundamental difference between the pagan and the biblical conceptions of religion. Religion, being personal fellowship with God, cannot be "learned" from men, but only by revelation (Matthew 16:17).
