When ye come to appear before me, who hath required this at your hand, to tread my courts? When ye come to appear - Instead of לראות leraoth, to appear, one MS. has לראות liroth, to see. See De Rossi. The appearing before God here refers chiefly to the three solemn annual festivals. See Exodus 23:14.
Tread my courts (no more) - So the Septuagint divide the sentence, joining the end of this verse to the beginning of the next: Πατειν την αυλην μου, ου προσθησεσθε; "To tread my court ye shall not add - ye shall not be again accepted in worship."
