II. They pray for the presence of God with him (v. 17): "Only the Lord thy God be with thee, to bless and prosper thee, and give thee success, as he was with Moses." Prayers and supplications are to be made for all in authority, 1 Tim. ii. 1, 2. And the best thing we can ask of God for our magistrates is that they may have the presence of God with them; this will make them blessings to us, so that in seeking this for them we consult our own interest. A reason is here intimated why they would obey him as they had obeyed Moses, because they believed (and in faith prayed) that God's presence would be with him as it was with Moses. Those that we have reason to think have favour from God should have honour and respect from us. Some understand it as a limitation of their obedience: "We will obey only as far as we perceive the Lord is with thee, but no further. While thou keepest close to God we will keep close to thee; hitherto shall our obedience come, but no further." But they were so far from having any suspicion of Joshua's deviating from the divine rule that there needed not such a proviso.
