Matthew Henry, Commentary on the Whole Bible… (1700s)
“ This angel is here called a watcher, or watchman, not only because angels by their nature are spirits, and therefore neither slumber nor sleep, but because by their office they are ministering spirits, and attend continually to their ministrations, watching all opportunities of serving their great Master. They, as watchers, encamp round those that fear God, to deliver them, and bear them up in their hands. ”
