Charles H. Spurgeon on Psalms 66:9

Which holdeth our soul in life. As the works of creation at first, and upholding all by his power and providence, are yoked together as works of a like wonder, vouchsafed the creation in common, Heb 1:2-3; so just in the like manner we find regeneration and perseverance joined, as the sum of all other works in this life. Thus "begotten again, "and "kept by the power of God to salvation, "are joined by the Apostle, 1Pe 1:3,5, "Called and preserved in Christ Jesus; "so in Jude 1:1... "Blessed be God, "says Peter, "who, according to his abundant mercy, hath begotten us again." And, O bless our God, ye people, which holdeth our souls in life, says the psalmist. Yea, if we do narrowly eye the words in either, both Peter and the psalmist do bless God for both at once. Blessed be God for "begetting us," who are also "kept by the power of God;" so it follows in Peter. In the psalmist both are comprehended in this one word:

1. Which putteth our souls in life (so the margin, out of the Hebrew), that is, who puts life into your soul at the first, as he did into Adam when he made him a living soul;

2. And then which holdeth, that is, continueth our souls in that life. So the translators render it also, according to the psalmist's scope, and O bless the Lord, saith the psalmist, for these and both these. Thomas Goodwin.
