<Psalm of praise.>> {a} I will extol thee, my God, O king; and I will bless thy name for ever and ever.

(a) He shows which sacrifices are pleasant and acceptable to God, even praise and thanksgiving and seeing that God still continues his benefits toward us, we ought never to be weary in praising him for the same.

Jamieson-Fausset-Brown Bible Commentary

PSALM 145

Ps 145:1-21. A Psalm of praise to God for His mighty, righteous, and gracious government of all men, and of His humble and suffering people in particular.

1, 2. (Compare Ps 30:1).

bless thy name-celebrate Thy perfections (Ps 5:11). God is addressed as king, alluding to His government of men.

Matthew Henry's Concise Commentary

145:1-9 Those who, under troubles and temptations, abound in fervent prayer, shall in due season abound in grateful praise, which is the true language of holy joy. Especially we should speak of God's wondrous work of redemption, while we declare his greatness. For no deliverance of the Israelites, nor the punishment of sinners, so clearly proclaims the justice of God, as the cross of Christ exhibits it to the enlightened mind. It may be truly said of our Lord Jesus Christ, that his words are words of goodness and grace; his works are works of goodness and grace. He is full of compassion; hence he came into the world to save sinners. When on earth, he showed his compassion both to the bodies and souls of men, by healing the one, and making wise the other. He is of great mercy, a merciful High Priest, through whom God is merciful to sinners.
