They seek me daily, and delight to know my ways (compare the picture drawn in Isaiah 1:11-15). We have there exactly the same representation of a people honouring God with their lips, but whose hearts are far from him—zealous in all the outward forms of religion, even making "many prayers" (Isaiah 1:15), but yet altogether an offence to God.
They are not conscious hypocrites—quite the reverse; they are bent on "doing righteousness," on not forsaking God's ordinance, on continually "approaching" him; but they are wholly without a proper sense of what religion is—they make it a matter of outward observance, and do not understand that it consists in the devotion of the heart.
That did righteousness, and forsook not; rather, that hath done righteousness, and hath not forsaken. The righteousness is, of course, forensic legal righteousness-the offering of the appointed sacrifices, the abstaining from unclean meats, the avoidance of external defilement, the payment of vows, the observance of the one appointed fast, and the like.
They ask of me the ordinances of justice. Either "they claim at God's hands righteous judgments on their enemies" (Delitzsch); or "they demand of God a fidelity to his covenant engagements correspondent to their own (assumed) fidelity to theirs."
They take delight in approaching to God. So the LXX; the Vulgate, Calvin, Vitringa, and Kay. Others prefer to render, "they desire the approach of God" (Knobel, Delitzsch, Cheyne); i.e. they desire that he will come to help them against their foes.
