Isaiah 58:2

The people indeed are zealous in the performance of their external religious duties, and imagine that this suffices to put them in a right relation to God. They are ostensibly as eager to know the divine will as if they were in reality, and not merely in profession, a people that practised righteousness. A somewhat strained interpretation has been put upon the verse by many modern commentators, who suppose that it refers to the people's desire for a speedy manifestation of Jehovah's righteousness in their favour. This feeling was no doubt in their minds, but it is not expressed here (see below).

they seek me i.e. enquire of me, the word used of consulting an oracle.

ordinances of justice not "righteous judgements" on the enemies and oppressors of Israel, but ordinances of righteousness, i.e. directions as to how righteousness is to be achieved.

they take delight in approaching to God R.V. they delight to draw near to God. Cf. ch. Isaiah 29:13; Psalms 73:28. To render "in the approach of God (to judgement)" is arbitrary, and unsuited to the verb "delight."
