I will sing unto the Lord as long as I live,.... Or, "in my life or lives ", throughout the whole of it. This was what the psalmist determined to do, let others do what they would; even sing songs of praise to the Lord; since he was the God of his life, who had fed him all his life long; from whom he had all the mercies of life, and by whom he had been followed with goodness and mercy all his days, and on whom his life and the comforts of it depended.
I will sing praise unto my God while I have my being: because he lived, and moved, and had his being in him; and it was continued to him, and he was upheld in it; and not only for his being, but for his well being; as for his temporal, so for his spiritual mercies, which he had from him as his God, as his covenant God; such as peace, pardon, righteousness, and eternal life: a view of God as our own God, such a view as Thomas had of Christ, when he said, "my Lord, and my God", is enough to make a man sing; and when the psalmist says he would do this as long as he lived and had a being, this is not to be understood as if this work would end with his life, or that he had no thought of praising him hereafter; but it signifies his constancy in this employment, while in the land of the living; knowing that in the grave he could not praise the Lord with his bodily organs as now; though he knew that this would be his eternal employ in the world of spirits, in his soul, during its separate state, and in soul and body after the resurrection.
