Summary: God does not seek great sacrifices but asks for justice, mercy, and humility.
With what shall I come before the LORD, and bow before God most high? Shall I come before him with burnt offerings, with calves a year old? Will the LORD be pleased with thousands of rams, with myriad streams of oil? Shall I give my first-born for my crime, the fruit of my body for the sin of my soul?
You have been told, O man, what is good, and what the LORD requires of you: Only to do the right and to love goodness, and to walk humbly with your God.
