'Exist' in the Bible

Oh spare me, that I may recover strength, before I go away, and exist no more." For the Chief Musician. A Psalm by David.

While I live, I will praise Yahweh. I will sing praises to my God as long as I exist.

Let every soul be in subjection to the higher authorities, for there is no authority except from God, and those who exist are ordained by God.

For first of all, when you come together in the assembly, I hear that divisions exist among you, and I partly believe it.
