'Perishing' in the Bible

Now the {length of time} that we had traveled from Kadesh Barnea until [the time when] we crossed the wadi of Zered [was] thirty-eight years, until the perishing of all of that generation; [that is], the men of war from the midst of the camp as Yahweh had sworn to them.

And thou hast answered and said before Jehovah thy God, A perishing Aramaean is my father! and he goeth down to Egypt, and sojourneth there with few men, and becometh there a nation, great, mighty, and numerous;

“The Lord will send upon you curses, confusion, and rebuke in everything that you undertake to do, until you are destroyed, perishing quickly because of the evil of your deeds, because you have turned away from Me.
