'Long' in the Bible

I think it right, as long as I am in this earthly tent, to inspire you by reminding you,

For they willingly forget [the fact] that the heavens existed long ago by the word of God, and the earth was formed out of water and by water,

[while you earnestly] look for and await the coming of the day of God. For on this day the heavens will be destroyed by burning, and the [material] elements will melt with intense heat!
