Proverbs 20:17-19

Names of God Bible

¹⁷ Food gained dishonestly tastes sweet to a person,
    but afterwards his mouth will be filled with gravel.
¹⁸ Plans are confirmed by getting advice,
    and with guidance one wages war.
¹⁹ Whoever goes around as a gossip tells secrets.
    Do not associate with a person whose mouth is always open.
