One shall not differentiate between good or bad, neither shall he make a substitute for it; and if he does substitute for it, then both it and the substitute shall be holy; it shall not be redeemed."New International Version
He must not pick out the good from the bad or make any substitution. If he does make a substitution, both the animal and its substitute become holy and cannot be redeemed.'"
