'Light' in the Bible

And there are there three sons of Zeruiah, Joab, and Abishai, and Asahel, and Asahel is light on his feet, as one of the roes which are in the field,

And they lift up Asahel, and bury him in the burying-place of his father, which is in Beth-Lehem, and they go all the night -- Joab and his men -- and it is light to them in Hebron.

And David riseth, and all the people who are with him, and they pass over the Jordan, till the light of the morning, till one hath not been lacking who hath not passed over the Jordan.

And as the light of morning he riseth, A morning sun -- no clouds! By the shining, by the rain, Tender grass of the earth!
