Ver. 42. Watch therefore, &c.] Laeti simus, non securi Let us be happy, not carefree. (Bernard). While Ishbosheth slept upon his bed at noon, Baanah and Rechab took away his head.

Satan works strongest on the fancy when the soul is drowsy. The spouse therefore promiseth to get up early, Song of Solomon 7:12, to shake off security, and not to be found henceforth supine and sluggish, but to stand upon her watch; as of Scanderbeg it is said, that from his first coming to Epirus, he never slept over two hours in a night, but with restless labour prosecuted his affairs.

Our Saviour pronounceth them three times happy that watch, Luke 12:37,38; Luke 12:43. a The blessed angels are called watchers, εγρηγοροι, Daniel 4:10 .
For ye know not what hour your Lord, &c.] He may haply come upon you, as Epaminondas did upon his sentinel, whom finding asleep, he thrust through with his sword, and being chidden for so severe a fact, he replied, I left him but as I found him, Talem eum reliqui, qualem inveni.
