Sometimes the cloud stayed only from night to morning. In the morning it moved, so they went. Sometimes it moved by day or by night. When it moved, they went. ➡️☁️♂️♀️
Sometimes the cloud remained only from evening until morning, and when it lifted in the morning, they would set out. Whether it was by day or by night, when the cloud was taken up, they would set out.
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.
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.
