The psalm opens with a call: the righteous are to rejoice in the Lord, for praise is fitting for the upright. They are invited to sing with the lyre and the harp of ten strings, with a new song and loud shouts. The reason is that the word of the Lord is upright and all his work is done in faithfulness; he loves righteousness and justice, and the earth is full of his steadfast love.
Then the psalm looks at creation. By the word of the Lord the heavens were made, and all their host by the breath of his mouth; he gathered the waters of the sea as in a jar and put the deeps in storehouses. All the earth is to fear the Lord. He spoke, and it came to be; he commanded, and it stood firm.
Next the psalm looks at the nations. The Lord frustrates the plans of the peoples, but his own plans stand forever; blessed is the nation whose God is the Lord. From heaven he looks on all mankind, sees all who dwell on earth and considers their deeds. No king is saved by a great army and no warrior by great strength, and the war horse is a false hope. The eyes of the Lord are on those who fear him, so the people wait for him, their help and shield, rejoice in his holy name and ask that his steadfast love be upon them.
