Proverbs 20:25 - Matthew Poole's English Annotations on the Holy Bible

It is a snare; it brings guilt and God's curse and vengeance upon him. That which is holy, i.e. those meats or drinks which were devoted or consecrated to God; under which one kind he comprehends and forbids all alienation of sacred or dedicated things from God to a man's private use or benefit; of which see Leviticus 27:9 Deuteronomy 23:21 Zechariah 3:8,9 Ac 5:1, &c. After vows to make inquiry; after a man hath made vows to consider whether he can possibly or may lawfullly keep them, and to invent or inquire of others all ways possible to break his vow, and to satisfy or deceive his conscience in so doing; which inquiry is justly censured as a sin and snare, because it is an evidence of a covetous or irreligious mind, and is the ready way and first step towards the open violation of it.
