Charles H. Spurgeon on Psalms 34:7

The angel of the Lord. The covenant angel, the Lord Jesus, at the head of all the bands of heaven, surrounds with his army the dwellings of the saints. Like hosts entrenched so are the ministering spirits encamped around the Lord's chosen, to serve and succour, to defend and console them. Encampeth round about them that fear him. On every side the watch is kept by warriors of sleepless eyes, and the Captain of the host is one whose prowess none can resist. And delivereth them. We little know how many providential deliverances we owe to those unseen hands which are charged to bear us up lest we dash our foot against a stone.
