Psalms 91:9

9Because thou, Jehovah, art my protection. He dwells at this length in commendation of the providence of God, as knowing how slow men naturally are to resort to God in a right manner; and how much they need to be stimulated to this duty, and to be driven from those false and worldly refuges in which they confide. There is a change of person frequently throughout this psalm: thus, in the first verse, he addresses God, and afterwards addresses himself. God he styles his protection, — in this manner, by his own example, recommending others to have recourse to God as their help. So, afterwards, he addresses himself, that he may be the better persuaded of the sincerity of his inward affection. The true method of testing our faith is to turn our thoughts inward upon ourselves, and, when no human eye sees us, to search our own spirits. If, not content with having to do with God only, we turn our eyes to men, it is almost impossible to prevent pride from insinuating itself into the room of faith. He speaks of accounting God to be his house or refuge, because he defends us from every evil, as in Psalms 90:1. This verse may be considered as connected with that which follows, and as stating the cause or reason of what is there asserted; for it is added, There shall no evil befall thee. And how are coming evils averted, but just by our resting with confidence in the protection of God? Troubles, it is true, of various kinds assail the believer as well as others, but the Psalmist means that God stands between him and the violence of every assault, so as to preserve him from being overwhelmed. The Divine guardianship is represented as extending to the whole household of the righteous; and we know that God comprehends under his love the children of such as he has adopted into his fatherly favor. Or, perhaps, the term may be taken in its simpler sense, and nothing more be intended than that those who choose God for their refuge will dwell safely in their houses.
