Magic for a cleric to hide a living body

I’m looking for a way that a cleric in 5E D&D can hide a living body, i.e., with a magic spell. Considering up to 5th-level spells, PHB rules only.

The use-case could be, for example: When an ally is fallen and we’d like to make sure that monsters don’t hit-to-kill the fallen party member, or drag them off mid-combat to hold as captives or finish them off.

I’ve scoured the cleric PHB listings and basically come up empty. What can we do in this case to render a living body unseen?
