1 A prayer of David. Hear, O LORD, and answer me, for I am poor and needy.

2 Guard my life, for I am devoted to you. You are my God; save your servant who trusts in you.

3 Have mercy on me, O Lord, for I call to you all day long.

4 Bring joy to your servant, for to you, O Lord, I lift up my soul.

5 You are forgiving and good, O Lord, abounding in love to all who call to you.

6 Hear my prayer, O LORD; listen to my cry for mercy.

7 In the day of my trouble I will call to you, for you will answer me.

8 Among the gods there is none like you, O Lord; no deeds can compare with yours.

9 All the nations you have made will come and worship before you, O Lord; they will bring glory to your name.

All nations – ‘David was not a believer in the theory that the world will grow worse and worse; and that the dispensation will wind up with general darkness, and idolatry … We look for a day when the dwellers in all lands shall learn righteousness, shall trust in the Saviour, shall worship thee alone, O God, “and shall glorify thy name.”’ (Spurgeon, The Treasury of David)

10 For you are great and do marvellous deeds; you alone are God.

11 Teach me your way, O LORD, and I will walk in your truth; give me an undivided heart, that I may fear your name.

12 I will praise you, O Lord my God, with all my heart; I will glorify your name for ever.

I will praise you – ‘Though nothing can add to God’s essential glory, yet praise exalts him in the eyes of others. When we praise God, we spread his fame and renown, we display the trophies of his excellency. In this manner the angels glorify him; they are the choristers of heaven, and do trumpet forth his praise. Praising God is one of the highest and purest acts of religion. In prayer we act like men; in praise we act like angels.’ (Thomas Watson)

13 For great is your love towards me; you have delivered me from the depths of the grave.

14 The arrogant are attacking me, O God; a band of ruthless men seeks my life—men without regard for you.

15 But you, O Lord, are a compassionate and gracious God, slow to anger, abounding in love and faithfulness.

16 Turn to me and have mercy on me; grant your strength to your servant and save the son of your maidservant.

The son of your maidservant – ‘In this Davidic psalm, the worshiper speaks of himself as “the son of Your female servant,” traditionally, “handmaid” (see also 116:16). Since the speaker was the king, the reference was to the “queen mother” who evidently could exercise considerable influence in the Judean and Israelite courts (1 Kg 2:19; 2 Ch 22:3). The records of the reigns of David’s descendants on the throne of Judah usually mention the name of the king’s mother (e.g., 1 Kg 14:31; 15:10; 22:42). Roman Catholic theologians sometimes point to these facts in support of the attention paid to the mother of Jesus, the Messiah, who also calls herself “the Lord’s slave” (Lk 1:38), or handmaid.’ (Apologetics Study Bible)

17 Give me a sign of your goodness, that my enemies may see it and be put to shame, for you, O LORD, have helped me and comforted me.
