Contradiction with Luke 6:30
This verse encourages giving to those who ask, contrasting the caution against surety for someone else found in Proverbs 6:1.
Luke 6:30: Give to every man that asketh of thee; and of him that taketh away thy goods ask [them] not again.
Contradiction with Matthew 5:42
Here, the advice is to give to those who ask and not refuse borrowers, which contradicts the warning in Proverbs 6:1 against entangling oneself in others' debts.
Matthew 5:42: Give to him that asketh thee, and from him that would borrow of thee turn not thou away.
