5 But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water.

Read 2 Peter 3:5 Using Other Translations

For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
For they deliberately overlook this fact, that the heavens existed long ago, and the earth was formed out of water and through water by the word of God,
They deliberately forget that God made the heavens long ago by the word of his command, and he brought the earth out from the water and surrounded it with water.
