Psalm 132: 4,5
I will not give sleep to mine eyes, or slumber to mine eyelids, Until I find out a place for the LORD, an habitation for the mighty God of Jacob.
I will not let you rest until you have given Me the place in your heart that I require of you. I will not let you sleep until you have filled your habitation (your heart) with My Word. Do not give sleep to your eyes, nor slumber to thine eyelids, until you have put Me in first place again. Thou cannot sleep because thine house is not filled with My Word, My soothing, peace-giving, sleep-bringing Word. I wake you in the night seasons because your lamp is running low.
Psalm 139:11 If I say, Surely the darkness shall cover me; even the night shall be light about me.
Psalm 139:12 Yea, the darkness hideth not from thee; but the night shineth as the day: the darkness and the light are both alike to thee.
