O give thanks unto the Lord
These are the words of David, either to the singers, or rather to the whole congregation of Israel, the seed of Abraham, and children of Jacob, ( Psalms 105:6 ) stirring them up to praise and thankfulness for their mercies, temporal and spiritual; for the Messiah they had hope and expectation of, typified by the ark now brought home; for the word and ordinances, and opportunities of waiting upon God in them; for heaven and happiness, figured by Canaan's land given them to enjoy. Or, "confess or celebrate the Lord" F24; his greatness and goodness: his being and perfections; his sovereignty over all creatures: confess him as your Creator, Benefactor, covenant God and Father; or, "confess to the Lord" F25 your sins and transgressions committed against him, his great grace and kindness to you, and your unworthiness to receive any favour from him.
Call upon his name;
as such may to advantage, who are thankful for what they have received from him; these may and ought to call upon him, or pray to him, in faith and fervency, with frequency and importunity, in the truth and sincerity of their souls; and at all times, especially in times of trouble. Some, as Aben Ezra, interpret it, proclaim his name, make it known to others; call upon them to serve and worship him. This sense is mentioned by Kimchi, and agrees with what follows:
make known his deeds among the people:
which are the effects of his counsel, wisdom, power, and goodness; such as the works of creation and providence, and especially of grace, and salvation; and which were to be published among the Heathen, for the glory of his name: and indeed the Gospel, which is ordered to be preached to all nations, is nothing else than a declaration of what Jehovah, Father, Son, and Spirit, have done and do.
F24 (hwhyl wdwx) celebrate Jehovam, Junius & Tremellius.
