appear before me - in the temple where the Shekinah, resting on the ark, was the symbol of God’s presence (Exo 23:15; Psa 42:2).
who hath required this - as if you were doing God a service by such hypocritical offerings (Job 35:7). God did require it (Exo 23:17), but not in this spirit (Mic 6:6, Mic 6:7).
courts - areas, in which the worshippers were. None but priests entered the temple itself.
