(1.) They have God with them, his Spirit and his special presence: Be strong, for I am with you, saith the Lord of hosts, v. 4. This he had said before (ch. i. 13), I am with you. But we need to have these assurances repeated, that we may have strong consolation. The presence of God with us, as the Lord of hosts, is enough to silence all our fears and to help us over all the discouragements we may meet with in the way of our duty. The Jews had hosts against them, but they had the Lord of hosts with them, to take their part and plead their cause. He is with them; for, [1.] He adheres to his promise. His covenant is inviolable, and he will be always theirs, and will appear and act for them, according to the word that he covenanted with them when they came out of Egypt. Though he chastens them for their transgressions with the rod, yet he will not make his faithfulness to fail. [2.] He dwells among them by his Spirit, the Spirit of prophecy. When he first formed them into a people he gave his good Spirit to instruct them (Neh. ix. 20); and still the Spirit, though often grieved and provoked to withdraw, remained among them. It was the Spirit of God that stirred up their spirits to come out of Babylon (Ezra i. 5), and now to build the temple, Hag. i. 14. Note, We have reason to be encouraged as long as we have the Spirit of God remaining among us to work upon us, for so long we have God with us to work for us.
