When ye come to appear before me. Mr. Cheyne translates, "to see my face;" but most other commentators (Gesenius, Delitzsch, Ewald, Kay) regard the phrase used as equivalent to that employed in Exodus 23:17; Exodus 34:23; Deuteronomy 16:16; and the passage as referring to that attendance in the temple at the three great annual festivals, which was required of all adult male Israelites.
The requirement of the Law was still observed in the letter, but not in the spirit. They came with no true religious object. Hence the question which follows: Who hath required this at your hand, to tread my courts?
This was not what God had enjoined—a mere bodily attendance, a trampling of his courts with their feet, when their hearts were far from him.
