'Selves' in the Bible

when they already sprout, ye know of your own selves, on looking at them, that already the summer is near.

and from among your own selves shall rise up men speaking perverted things to draw away the disciples after them.

examine your own selves if ye be in the faith; prove your own selves: do ye not recognise yourselves, that Jesus Christ is in you, unless indeed ye be reprobates?
