Psalms 37:40

And the Lord shall help them - He will interpose to defend them when they are in danger and in trouble.

And deliver them - Rescue them from their dangers, and from the power of the wicked.

He shall deliver them from the wicked - From all the attempts of the wicked to destroy them.

And save them - Or, preserve them. He will keep them to everlasting life.

Because they trust in him - They rely on him, and not on themselves. This verse is a summing up of the sentiments of the psalm, and is designed to confirm the main thought which runs through it, to wit, that we should not fret, or complain, or repine at the prosperity of wicked men, Psalms 37:1. The reason ultimately assigned for this is, that whatever may be the danger of the righteous from the designs of wicked men, they will in the end be safe. It will go well with them, for the Lord will keep them. The general course of thought in the psalm is, that, whatever prosperity the wicked now have, it is temporary, for they will soon be cut off; and that whatever troubles now come upon the righteous, they too are temporary, and that their “hereafter” - “their futurity” - will be blessedness and peace. There is a moral government: God is the friend of the righteous; along the path of the present life there are proofs that he is so, and beyond the present life he will show himself to be so in their eternal peace.

He is the enemy of the wicked; there are evidences in the present life that he is so, and this will be fully and finally manifested in their destruction in the future world. The argument in the psalm, indeed, is mainly drawn from the “present life,” from what there is to encourage virtue and goodness in the blessings which religion scatters on earth, and by the peaceful termination of the course - as well as from what there is to discourage wickedness and vice, in the fact that the wicked will be cut down and pass away. The argument is, that if this life were all, there are encouragements here to virtue and goodness. In Psalms 73, which in some respects resembles this psalm, the argument which satisfied the mind of the troubled psalmist - troubled at the prosperity of the wicked - is drawn mainly from the future world. Here it is drawn chiefly from the present life; and the main thought here - the practical lesson from the psalm - is, that even with reference to the life that now is - to its security, to its peace, to its blessedness, and to its happy close - it is an advantage to be righteous. It is better to have God for our friend in life, and our support in death, than to have all the external prosperity of wicked men.
