Albert Barnes Commentary Micah 6:6-7

"Wherewith shall I come before Jehovah, and bow myself before the high God? shall I come before him with burnt-offerings, with calves a year old? will Jehovah be pleased with thousands of rams, [or] with ten thousands of rivers of oil? shall I give my first-born for my transgression, the fruit of my body for the sin of my soul?" — Micah 6:6-7 (ASV)

With what shall I come before the Lord? - The people, thus accused, burst in, as people often do, with professions that they would no longer be ungrateful; that they will do anything, everything—except what they ought. With them it will be only “Ask and have.” They wish only to know, with what they will come? They would anticipate Him, eagerly fulfilling His wishes; they would, with all the submission of a creature, bow, prostrate themselves before God. They acknowledge His High Majesty, who dwells on high, the Most High God, and would humble themselves before His lofty greatness, if they only knew “how” or “with what.”

They would give of their best: sacrifices, the choicest of their kind, which would be wholly His; whole-burnt-offerings, offered exactly according to the law, bullocks of a year old (Leviticus 9:2–3). Then too, the next choice offering: the rams. These, as they were offered for the whole people on very solemn occasions, would come in vast multitudes, thousands or ten thousands. The oil which accompanied the burnt sacrifice would flow in rivers. Indeed, even more, they would not withhold their sons, their firstborn sons, from God—who were part of themselves—or any fruit of their own bodies.

They enhance the offering by naming the tender relation to themselves (Deuteronomy 28:53). They would offer everything (even what God forbade), excepting only what He alone asked for: their heart, its love, and its obedience.

The form of their offering reveals this: they ask zealously, “With what shall I come?” It is only an outward offering, something they would bring. Hypocritical eagerness! A sin against light!

For to inquire further, when God has already revealed something, is to deny that He has revealed it. It comes from the wish that He had not revealed what He has revealed: “Whoever, after he has found the truth, discusses anything further, seeks a lie.” God had told them long before, from the time He made them His people, what He desired of them. So Micah answers:
