Leviticus 22:23
Either a bullock or a lamb that hath any thing superfluous or lacking in his parts, that mayest thou offer for a freewill offering; but for a vow it shall not be accepted. Either a bullock or a lamb that hath any thing superfluous or lacking in his parts, that mayest thou offer for a freewill offering; but for a vow it shall not be accepted.
A bullock or a lamb that has anything superfluous or lacking in its parts may be offered for a freewill offering, but for a vow it shall not be accepted. In its context the sacrificial animals had to be carefully examined and rejected for even the least blemish or impurity, so that the offering brought was sound and valuable and free from defects.
The requirement teaches that what is presented to God must be the best, worthy and acceptable, not lame or given grudgingly. The principle applies to providing a suitable and comfortable place of worship and to giving generously toward it. It illustrates that the body offered to God as a living sacrifice must be holy and acceptable rather than degraded by harmful habits.
