2 Corinthians 4:18 YLT

¹⁶  wherefore, we faint not, but if also our outward man doth decay, yet the inward is renewed day by day;

¹⁷  for the momentary light matter of our tribulation, more and more exceedingly an age-during weight of glory doth work out for us --

¹⁸  we not looking to the things seen, but to the things not seen; for the things seen 'are' temporary, but the things not seen 'are' age-during.
