'Selves' in the Bible

We wait [expectantly] for the Lord;He is our help and our shield.

Listen carefully, all you who kindle your own fire [devising your own man-made plan of salvation],Who surround yourselves with torches,Walk by the light of your [self-made] fireAnd among the torches that you have set ablaze.But this you will have from My hand:You will lie down in [a place of] torment.

and say, ‘Thus says the Lord God, “Woe to the women who fasten magic (protective) charms on all wrists and make veils for the heads of those of every stature to capture [human] lives! Will you capture the lives of My people but keep your own?

And Peter said to them, “Repent [change your old way of thinking, turn from your sinful ways, accept and follow Jesus as the Messiah] and be baptized, each of you, in the name of Jesus Christ because of the forgiveness of your sins; and you will receive the gift of the Holy Spirit.

even from among your own selves men will arise, speaking perverse and distorted things, to draw away the disciples after themselves [as their followers].

Test and evaluate yourselves to see whether you are in the faith and living your lives as [committed] believers. Examine yourselves [not me]! Or do you not recognize this about yourselves [by an ongoing experience] that Jesus Christ is in you—unless indeed you fail the test and are rejected as counterfeit?
