I will not give sleep to mine eyes - There is no difference here between the words sleep and slumber. The meaning is, that the house of the Lord should be his first care.

I will not give sleep to mine eyes, or slumber to mine eyelids. Not that he never would or did take any sleep till this thing was brought about he had so much at heart; but that he could not and would not suffer himself to sleep comfortably and quietly because of it. Aben Ezra interprets it of sleep at noon; the phrases express his great desire and solicitude to have this affair accomplished, and his eager and diligent pursuit of it; see Proverbs 6:4; of the eager desire of Christ to suffer and die for his people, that they might be brought near to God, and be his dwelling place, see Luke 12:50.
