When we practice “the hidden life” we are not alone, for God is with us and compensates for our inadequacies. This paragraph emphasizes that we need not be afraid because the Lord and His angels watch over us. In the ancient Near East, travel was dangerous, unless you were protected by armed guards. (It is not much different in some large cities today.) “Terror by night” could mean simply “the fear of the dark” and of what can happen in the darkness. Contaminated water and food, plus an absence of sound health measures, made it easy to contract diseases by day or by night, although “the destruction that lays waste at noon” (v. 6 nasb) could refer to the effects of the burning rays of the sun.
Verses 7–8 read like the description of a battle and may have a direct relationship to the covenant promises God made with Israel (Lev. 26:8; Deut. 32:30). With their own eyes, Israel saw the grief of the Egyptians over their firstborn who died on Passover night (Ex. 12:29–30), and they also saw the Egyptian army dead on the shore of the Red Sea (Ex. 14:26–31), yet no harm came to the people of Israel. God’s angel went before them to prepare the way and to lead the way (Ex. 23:20). Satan quoted part of verses 11–12 when he tempted Jesus in the wilderness (Matt. 4:6), and the Lord responded with Deuteronomy 6:16. If the Father had commanded Jesus to jump from the temple pinnacle, then the angels would have cared for Jesus, but to jump without the Father’s command would have been presumption, not faith, and that would be tempting the Father. In Scripture, the lion and serpent (cobra) are images of Satan (1 Peter 5:8; Gen. 3; 2 Cor. 11:3; Rev. 12:9; 20:2; and see Luke 10:19; Rom. 16:20). In the ancient Near East, both were dangerous enemies, especially for travelers walking along the narrow paths.
