Psalms 18:46

“The Lord liveth--contrasts Him with idols (Co1 8:4).”

“The Lord liveth - Yahweh - the name used here - is often described as the living God in contradistinction to idols, who are represented as without life, Deuteronomy 5:26; Joshua 3:10; 2 Kings 19:4; Psalms 42:2; Matthew 16:16; 1 Thessalonians 1:9. Compare Psalms 115:5; Psalms 135:16. It is probably in allusion to this idea that the phrase “The Lord liveth” is used here.

“(Heb.: 18:47-49) The hymn now draws towards the end with praise and thanksgiving for the multitude of God's mighty deeds, which have just been displayed. Like the (צוּרי) בּרוּך which is always doxological, חי ה (vivus Jahve) is meant as a predicate clause, but is read with the accent of an exclamation just as in the formula of an oath, which is the same expression; and in the present instance it has a doxological meaning.
