'Light' in the Bible

And this is but a light thing in the sight of Jehovah: he will also deliver the Moabites into your hand.

Then they said one to another, We do not well; this day is a day of good tidings, and we hold our peace: if we tarry till the morning light, punishment will overtake us; now therefore come, let us go and tell the king's household.

And Hezekiah answered, It is a light thing for the shadow to decline ten steps: nay, but let the shadow return backward ten steps.
