Psalm 50:16-23 and Amos 2:6-10, 13-16

Psalm 50:16-23
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. 
Amos 2:6-10, 13-16
6 Thus says the Lord: For three wicked deeds of Israel, and for four, I will not convert him, in so far as he has sold the just for silver and the poor for shoes.
7 They grind the heads of the poor into the dust of the earth, and they divert the way of the humble. And the son, as well as his father, have gone to the same girl, so that they outrage my holy name.
8 And they have lain on garments taken in pledge next to every altar. And they drank the wine of the damned in the house of their God.
9 Yet I exterminated the Amorites before their face, whose height was like the height of cedars, and whose strength was like the oak. And I crushed his fruit from above and his roots below.
10 It is I who caused you to ascend from the land of Egypt, and I led you in the wilderness for forty years, so that you might possess the land of the Amorite.
​13 Behold, I will creak under you, just as a wagon creaks that is laden with hay.
14 And flight will perish from the swift, and the strong will not maintain his strength, and the healthy will not save his life.
15 And one holding the bow will not stand firm, and the swift of foot will not be saved, and the rider on the horse will not save his life.
16 And the stout of heart among the strong will flee away naked in that day, says the Lord.
