'Decayeth' in the Bible

As the waters fail from the sea, and the flood decayeth and drieth up:

By much slothfulness the building decayeth; and through idleness of the hands the house droppeth through.

Jesus saith, Take ye away the stone. Martha, the sister of him that was dead, saith unto him, Lord, by this time the body decayeth; for he hath been dead four days.

In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
