An ox or a sheep that has a leg that is too long or is stunted you may indeed present as a voluntary offering, but it will not be acceptable as a votive offering.
Every Israelite man and woman brought to the Lord such voluntary offerings as they thought best, for the various kinds of work which the Lord, through Moses, had commanded to be done. The Artisans.
One that is blind or lame or maimed, or one that has running lesions or sores or scabs, you shall not offer to the Lord; do not put such an animal on the altar as an oblation to the Lord.
When you offer a blind animal for sacrifice, is there no wrong in that? When you offer a lame or sick animal, is there no wrong in that? Present it to your governor! Will he be pleased with you—or show you favor? says the Lord of hosts.
