'Light' in the Bible

Then they picked up Asahel and buried him in the grave of his father, which [was at] Bethlehem. Joab and his men went all that night {[arriving] in Hebron at first light}.

So David and all the people who [were] with him set out, and they crossed over the Jordan until morning light until {there was no one} missing who had not crossed over the Jordan.

Like the light of [the] morning when the sun rises, shining with no clouds, [bringing] vegetation from the earth apart from rain.'
