I reckoned till morning, that, as a lion, so will he break all my bones: from day even to night wilt thou make an end of me.
I reckon — When I could not rest all the night even 'till morning, my thoughts were presaging that God would instantly break me to pieces, and the like thoughts followed me from morning 'till evening.
 O Lord, by these things men live, and in all these things is the life of my spirit: so wilt thou recover me, and make me to live.
By these — By thy promises, and thy performance of them; therefore it is not strange, that one word of God hath brought me back from the jaws of death.
 For the grave cannot praise thee, death can not celebrate thee: they that go down into the pit cannot hope for thy truth.
Praise — The dead are not capable of glorifying thy name among men upon earth. They cannot expect nor receive the accomplishment of thy promised goodness in the land of the living.
 The LORD was ready to save me: therefore we will sing my songs to the stringed instruments all the days of our life in the house of the LORD.
Was ready — Was a present help.
