Thou, O Jehovah! art near. He encourages himself from the consolatory consideration, that God, when he sees his own people sore pressed, comes forward, seasonably to afford them succor; even as Paul on this subject says, "Be not over-careful, the Lord is at hand, let your moderation be known to all men " (Philippians 4:5) The concluding sentence of the verse is to this effect, That God never forsakes nor disappoints his people in their necessity, because he is true to his promises; and in them he assures us, that the welfare of his people will always be the object of his care. That therefore we may be fully persuaded that the hand of God is always ready to repulse the assaults of our enemies, let us retain a settled belief of the truth, that he does not in vain promise in his word to be the guardian of our welfare.

Thou art near, O Lord - God was present with him; he was ready to hear his cry; he was at hand to save him. Compare Psalm 145:18. The psalmist had the assurance, springing from deep feeling, and the conscious presence of God, which the people of God often have, that God is very near to them; that he is ready to hear them; that their prayers are answered; that they are in the presence of a heavenly Friend. Such are among the precious experiences of the life of a religious man.
And all thy commandments are truth - All that thou hast ordained; all that thou hast promised. The psalmist felt this. He was experiencing the truth of what God had assured him of. Not a doubt came into his mind - for God was near him. This conviction that God is "near" us - this manifestation of God to the soul as a present God - is one of the most certain assurances to our own minds of the truth of religion, and of our acceptance with him.

Thou art near - As they are near to destroy, so art thou near to save. When the enemy comes in as a flood, the Spirit of the Lord lifts up a standard against him.

Thou art near, O Lord,.... This was the comfort of the psalmist, that though his enemies drew nigh with a mischievous design upon him, yet his God was also near, and nearer than they; he was near as to relation to him, being his God and Father; near as to union, the bond of which is his everlasting love, which can never be dissolved; near as to communion, which he admits all his people to at one time or another; so that they are said to be "a people near unto the Lord"; Psalm 148:14; and near as to his gracious presence, and the divine assistance he affords; he is a present help in time of need; he is nigh to all that call on him in truth, and in all things in which they do call upon him for, Psalm 145:18;
and all thy commandments are truth; not only the precepts of the word of God, but his covenant, and the promises of it; the word which he has commanded to a thousand generations, Psalm 105:8; and even the whole word of God, doctrines and duties; see John 17:17.
