1 Samuel 15:16-23
16Then Samuel said to Saul, "Stop! I will tell you what the LORD said to me this night." And he said to him, "Say on." 17And Samuel said, "Though you are little in your own eyes, are you not the head of the tribes of Israel? The LORD anointed you king over Israel. 18And the LORD sent you on a mission, and said, `Go, utterly destroy the sinners, the Amal'ekites, and fight against them until they are consumed.' 19Why then did you not obey the voice of the LORD? Why did you swoop on the spoil, and do what was evil in the sight of the LORD?" 20And Saul said to Samuel, "I have obeyed the voice of the LORD, I have gone on the mission on which the LORD sent me, I have brought Agag the king of Am'alek, and I have utterly destroyed the Amal'ekites. 21But the people took of the spoil, sheep and oxen, the best of the things devoted to destruction, to sacrifice to the LORD your God in Gilgal." 22And Samuel said, "Has the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams. 23For rebellion is as the sin of divination, and stubbornness is as iniquity and idolatry. Because you have rejected the word of the LORD, he has also rejected you from being king."
Psalms 50:8-9, 16-17, 21, 23
8I do not reprove you for your sacrifices; your burnt offerings are continually before me. 9I will accept no bull from your house, nor he-goat from your folds. 16But to the wicked God says: "What right have you to recite my statutes, or take my covenant on your lips? 17For you hate discipline, and you cast my words behind you. 21These things you have done and I have been silent; you thought that I was one like yourself. But now I rebuke you, and lay the charge before you. 23He who brings thanksgiving as his sacrifice honors me; to him who orders his way aright I will show the salvation of God!"
18Now John's disciples and the Pharisees were fasting; and people came and said to him, "Why do John's disciples and the disciples of the Pharisees fast, but your disciples do not fast?" 19And Jesus said to them, "Can the wedding guests fast while the bridegroom is with them? As long as they have the bridegroom with them, they cannot fast. 20The days will come, when the bridegroom is taken away from them, and then they will fast in that day. 21No one sews a piece of unshrunk cloth on an old garment; if he does, the patch tears away from it, the new from the old, and a worse tear is made. 22And no one puts new wine into old wineskins; if he does, the wine will burst the skins, and the wine is lost, and so are the skins; but new wine is for fresh skins."
