Psalm 50:8-23 and Isaiah 1:10, 16-20

Psalm 50:8-23
8 I will not reprove you for your sacrifices. Moreover, your holocausts are ever in my sight.
9 I will not accept calves from your house, nor he-goats from your flocks.
10 For all the wild beasts of the forest are mine: the cattle on the hills and the oxen.
11 I know all the flying things of the air, and the beauty of the field is with me.
12 If I should be hungry, I would not tell you: for the whole world is mine, and all its plentitude.
13 Shall I gnaw on the flesh of bulls? Or would I drink the blood of goats?
14 Offer to God the sacrifice of praise, and pay your vows to the Most High.
15 And call upon me in the day of tribulation. I will rescue you, and you will honor me.
16 But to the sinner, God has said: Why do you discourse on my justices, and take up my covenant through your mouth?
17 Truly, you have hated discipline, and you have cast my sermons behind you.
18 If you saw a thief, you ran with him, and you have placed your portion with adulterers.
19 Your mouth has abounded with malice, and your tongue has concocted deceits.
20 Sitting, you spoke against your brother, and you set up a scandal against your mother's son.
21 These things you have done, and I was silent. You thought, unjustly, that I ought to be like you. But I will reprove you, and I will set myself against your face.
22 Understand these things, you who forget God; lest at any time, he might quickly take you away, and there would be no one to rescue you.
23 The sacrifice of praise will honor me. And in that place is the journey by which I will reveal to him the salvation of God.
Isaiah 1:10, 16-20
10 Listen to the Word of the Lord, you leaders of the people of Sodom. Listen closely to the law of our God, O people of Gomorrah.
​16 Wash, become clean, take away the evil of your intentions from my eyes. Cease to act perversely.
17 Learn to do good. Seek judgment, support the oppressed, judge for the orphan, defend the widow.
18 And then approach and accuse me, says the Lord. Then, if your sins are like scarlet, they shall be made white like snow; and if they are red like vermillion, they shall become white like wool.
19 If you are willing, and you listen to me, then you will eat the good things of the land.
20 But if you are not willing, and you provoke me to anger, then the sword will devour you. For the mouth of the Lord has spoken.
