“That it may be well with thee, and thou mayest live long on the earth.”
King James Version (KJV)
6:3 That thou mayest live long upon the earth - This is usually fulfilled to eminently dutiful children; and he who lives long and well has a long seed - time for the eternal harvest. But this promise, in the Christian dispensation, is to be understood chiefly in a more exalted and Spiritual sense.
Eph 6:3 That it may be well with thee, and thou mayest live long on the earth. Quoted from Ex 20:12. This is the promise. A temporal blessing was conditioned upon the promise to Israel, and to honor parents still brings blessing.
