'Sometimes' in the Bible

Sometimes the cloud was resting on the House for two or three days; then, by the order of the Lord, they kept their tents in that place, and when the Lord gave the order they went on.

And sometimes the cloud was there only from evening to morning; and when the cloud was taken up in the morning they went on their journey again: or if it was resting there by day and by night, whenever the cloud was taken up they went forward.
