Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God. Psalm 90:2
Before the mountains were brought forth – Before the earth brought forth or produced the mountains. In the description of the creation it would be natural to represent the mountains as the first objects that appeared, as emerging from the waters; and, therefore, as the “first” or “most ancient” of created objects. The phrase, therefore, is equivalent to saying, Before the earth was created. The literal meaning of the expression, “were brought forth,” is, in the Hebrew, “were born.” The mountains are mentioned as the most ancient things in creation, in Deuteronomy 33:15. Compare Genesis 49:26; Habakkuk 3:6.
Or ever thou hadst formed – literally, “hadst brought forth.” Compare Job 39:1.
The earth and the world – The word “earth” here is used to denote the world as distinguished either from heaven Genesis 1:1, or from the sea Genesis 1:10. The term “world” in the original is commonly employed to denote the earth considered as “inhabited,” or as capable of being inhabited – a dwelling place for living beings.
Even from everlasting to everlasting – From duration stretching backward without limit to duration stretching forward without limit; that is, from eternal ages to eternal ages; or, forever.
