Verse 3. - Let Israel hope in the Lord from henceforth and forever (comp. Psalm 130:7). Israel is exhorted to have like confidence and trust in God as the psalmist.
131:1-3 The psalmist's humility. Believers encouraged to trust in God. - The psalmist aimed at nothing high or great, but to be content in every condition God allotted. Humble saints cannot think so well of themselves as others think of them. The love of God reigning in the heart, will subdue self-love. Where there is a proud heart, there is commonly a proud look. To know God and our duty, is learning sufficiently high for us. It is our wisdom not to meddle with that which does not belong to us. He was well reconciled to every condition the Lord placed him in. He had been as humble as a little child about the age of weaning, and as far from aiming at high things; as entirely at God's disposal, as the child at the disposal of the mother or nurse. We must become as little children, Mt 18:3. Our hearts are desirous of worldly things, cry for them, and are fond of them; but, by the grace of God, a soul that is made holy, is weaned from these things. The child is cross and fretful while in the weaning; but in a day or two it cares no longer for milk, and it can bear stronger food. Thus does a converted soul quiet itself under the loss of what it loved, and disappointments in what it hoped for, and is easy whatever happens. When our condition is not to our mind, we must bring our mind to our condition; then we are easy to ourselves and all about us; then our souls are as a weaned child. And thus the psalmist recommends confidence in God, to all the Israel of God, from his own experience. It is good to hope, and quietly to wait for the salvation of the Lord under every trial.
Let Israel hope in the Lord from henceforth and for ever. What he did himself, and found it good for him to do, that he knew was good for others, and therefore exhorts and encourages to it, to hope in the Lord and wait for his salvation; and which should be done constantly, and to the end of life, or till the thing hoped for is enjoyed; see Hebrews 3:6. Perhaps some respect is here had to the people of Israel, especially the friends of David, who were weary of Saul's government, and impatient to have David on the throne; whom he advises to wait patiently, and not take any indirect steps to bring it about, but leave it with God, and hope and trust in him; compare with this 1 Samuel 24:7; See Gill on Psalm 130:7.
