'Existence' in the Bible

that sendest ambassadors over the sea, and in vessels of papyrus upon the waters, saying, Go, swift messengers, to a nation scattered and ravaged, to a people terrible from their existence and thenceforth; to a nation of continued waiting and of treading down, whose land the rivers have spoiled!

In that time shall a present be brought unto Jehovah of hosts of a people scattered and ravaged, and from a people terrible from their existence and thenceforth, a nation of continued waiting and of treading down, whose land the rivers have spoiled, ... to the place of the name of Jehovah of hosts, the mount Zion.

“Even from eternity I am He,And there is no one who can rescue from My hand;I act, and who can revoke or reverse it?”

Come near to me, and give ear to this; from the start I did not keep it secret; from the time of its coming into existence I was there: and now the Lord God has sent me, and given me his spirit.
