Moses began by attributing eternality to Yahweh. All generations of believers have found Him to be a protective shelter from the storms of life. God existed before He created anything, even the "world" (Heb. tebel, lit. the productive earth). This Hebrew word is a poetic synonym for "earth" (Heb. "eres, i.e, the planet).

God outlasts man. He creates him and then sees him return to "dust" (Heb. dakka, lit. pulverized material). From God"s eternal perspective1 ,000 years are as a day is to us ( 2 Peter 3:8). This does not mean that God is outside time. Time simply does not bind or limit Him as it does us. All events are equally vivid to Him. Time is the instrument we use to mark the progression and relationship of events. God"s personal timeline has no end, whereas ours stretches only about70 years before we die. [source][source][source]
Human life is therefore quite brief compared to God"s eternality. A watch in the night was about four hours long. The years of our lives sweep past, as something a flood might carry off, before we can retrieve them. Our lifetime is similar to one day from God"s perspective or as a flower that only blooms for one day. Life is not only brief but frail. [source][source][source]
