Psalm 18:31-51 and Sirach 47:2-11

Psalm 18:31-51
31 As for my God, his way is undefiled. The eloquence of the Lord has been examined by fire. He is the protector of all who hope in him.
32 For who is God, except the Lord? And who is God, except our God?
33 It is God who has wrapped me with virtue and made my way immaculate.
34 It is he who has perfected my feet, like the feet of deer, and who stations me upon the heights.
35 It is he who trains my hands for battle. And you have set my arms like a bow of brass.
36 And you have given me the protection of your salvation. And your right hand sustains me. And your discipline has corrected me unto the end. And your discipline itself will teach me.
37 You have expanded my footsteps under me, and my tracks have not been weakened.
38 I will pursue my enemies and apprehend them. And I will not turn back until they have failed.
39 I will break them, and they will not be able to stand. They will fall under my feet.
40 And you have wrapped me with virtue for the battle. And those rising up against me, you have subdued under me.
41 And you have given the back of my enemies to me, and you have destroyed those who hated me.
42 They cried out, but there was none to save them, to the Lord, but he did not heed them.
43 And I will crush them into dust before the face of the wind, so that I will obliterate them like the mud in the streets.
44 You will rescue me from the contradictions of the people. You will set me at the head of the Gentiles.
45 A people I did not know has served me. As soon as their ears heard, they were obedient to me.
46 The sons of foreigners have been deceitful to me, the sons of foreigners have grown weak with time, and they have wavered from their paths.
47 The Lord lives, and blessed is my God, and may the God of my salvation be exalted:
48 O God, who vindicates me and who subdues the people under me, my liberator from my enraged enemies.
49 And you will exalt me above those who rise up against me. From the iniquitous man, you will rescue me.
50 Because of this, O Lord, I will confess to you among the nations, and I will compose a psalm to your name:
51 magnifying the salvation of his king, and showing mercy to David, his Christ, and to his offspring, even for all time.
​Sirach 47:2-11
2 And just as fat is separated from meat, so was David separated from the sons of Israel.
3 He played with lions, as if with lambs, and he acted similarly with bears, as if they were lambs of the flock, in his youth.
4 Did he not kill the giant, and take away the reproach from his people?
5 By lifting up his hand, with a stone in a sling, he threw down the boasting of Goliath.
6 For he called upon the Almighty Lord, and he swore with his right hand to take away the mighty man of war, and to exalt the horn of his people.
7 So he glorified him amid ten thousand, and he praised him with the blessings of the Lord, by offering him a crown of glory.
8 For he crushed the enemies on every side, and he eradicated his adversaries, the Philistines, even to this day. He broke their horn, even for all time.
9 In all his works, he gave thanks to the Holy One, to the Most High, with words of glory.
10 With all his heart, he praised the Lord and he loved God, who made him and who gave him power against his enemies.
11 And he appointed singers to stand opposite the altar, and by their voices he provided sweet music.
