'Leave' in the Bible

So I sent messengers to them, replying "I am involved in a great endeavor, so I can't leave. Why should the work stop while I leave it to come down to you?"

You, in your great compassion, did not abandon them in the wilderness. The pillar of cloud did not leave them in daylight, in order to provide light for them on the path they took. Nor did the pillar of fire abandon them at night, in order to provide light for them and lead them on the path they took.
