“Lord, you have been our dwelling place in all generations. Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God” (Ps. 90:1-2, ESV). The words, “dwelling place” (Heb. ma’on), means “refuge.” (TWOT) The phrase, “all generations,” literally reads in Hebrew, bedor wador, “by generation to generation.” The singular noun, “generation” (Heb. dor), means, the “period” (BDB) of a man’s lifetime from conception to death. (TWOT) Thus, Moses is saying that the Lord has been our refuge from lifetime to lifetime, from generation to generation.
In v. 2, Moses said that even before God created the world, God is “from everlasting to everlasting.” We see a play of words here. As God is from everlasting to everlasting, so is He Israel’s refuge “from generation to generation.”
This means that this timeless God is their refuge within the timeframe of their lives. Within the limited timeframe of their lives, Moses finds the eternal, timeless God as their enduring refuge.
Now try to think about it. You are time-bound and therefore, temporary. You live in the limited timeframe of your life. But this eternal, timeless God has chosen to enter into your temporal timeframe, to help you, to be there for you.
