2 Corinthians 1:20-23

For how many soever be the promises of God, in him is the yea: wherefore also through him is the Amen, unto the glory of God through us. Now he that establisheth us with you in Christ, and anointed us, is God; who also sealed us, and gave us the earnest of the Spirit in our hearts. But I call God for a witness upon my soul, that to spare you I forbare to come unto Corinth.
