ASV

And sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they journeyed: or if it continued by day and by night, when the cloud was taken up, they journeyed.

KJV

And so it was, when the cloud abode from even unto the morning, and that the cloud was taken up in the morning, then they journeyed: whether it was by day or by night that the cloud was taken up, they journeyed.
