Because a vow must be of such things as wherein the vower hath a particular interest, as his owne, though that interest cannot be any other then derivative from, and dependent on God; but such things as were not dedicated to God for sacrifice, might, or rather must be redeemed, whether of man or uncleane beasts. And though vowing and redeeming seeme contrary acts, yet a vow in one sense might be made with a purpose of redemption in another sense; as Samuel was vowed to God for service, yet with an intent to redeeme him from sacrifice, 1 Samuel 1:11.
