American Standard Version (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.
King James Version (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.
