Heb 6:16.   For men verily swear by the greater: and an oath for confirmation is to them an end of all strife. 2 Cor 1:23.   Moreover I call God for a record upon my soul, that to spare you I came not as yet unto Corinth. Isa 65:16.   That he who blesseth himself in the earth shall bless himself in the God of truth; and he that sweareth in the earth shall swear by the God of truth; because the former troubles are forgotten, and because they are hid from mine eyes.
