1 Samuel 15:20-22

‘But I did obey the LORD,’ Saul said. ‘I went on the mission the LORD assigned me. I completely destroyed the Amalekites and brought back Agag their king. The soldiers took sheep and cattle from the plunder, the best of what was devoted to God, in order to sacrifice them to the LORD your God at Gilgal.’ But Samuel replied: ‘Does the LORD delight in burnt offerings and sacrifices as much as in obeying the LORD? To obey is better than sacrifice, and to heed is better than the fat of rams.
