Bible Verses About Priests: No blemished or defective persons could be consecrated

Say to Aaron: Whosoever of thy seed throughout their families, hath a blemish, he shall not offer bread to his God.

Neither shall he approach to minister to him: If he be blind; if he be lame; if he have a little, or a great, or a crooked nose;

If his foot, or if his hand be broken;

If he be crookbacked; or blear eyed; or have a pearl in his eye, or a continual scab, or a dry scurf in his body, or a rupture.

Whosoever of the seed of Aaron the priest hath a blemish: he shall not approach to offer sacrifices to the Lord, nor bread to his God.

He shall eat nevertheless of the loaves that are offered in the sanctuary.

Yet so that he enter not within the veil, nor approach to the altar: because he hath a blemish, and he must not defile my sanctuary. I am the Lord who sanctify them.
