NET
16 Whoever pronounces a blessing in the earth will do so in the name of the faithful God; whoever makes an oath in the earth will do so in the name of the faithful God. For past problems will be forgotten; I will no longer think about them.
Darby
16 so that he who blesseth himself in the land shall bless himself by the God of truth; and he that sweareth in the land shall swear by the God of truth: because the former troubles shall be forgotten, and because they shall be hidden from mine eyes.
KJV
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.
