Albert Barnes Commentary Proverbs 20:25

"It is a snare to a man rashly to say, [It is] holy, And after vows to make inquiry." — Proverbs 20:25 (ASV)

Better, It is a snare to a man to utter a vow (of consecration) rashly, and after vows to inquire whether he can fulfill them. Both clauses are a protest against the besetting sin of rash and hasty vows. Compare the marginal reference.
