My soul shall boast in Yahweh. The humble shall hear of it, and be glad.
My soul shall make her boast in the Lord. Boasting is a very natural propensity, and if it were used as in this case, the more it were indulged the better. The exultation of this verse is no mere tongue bragging, "the soul" is in it, the boasting is meant and felt before it is expressed. What scope there is for holy boasting in Jehovah!
We cannot justify David's dissimulation; it ill became an honest man to feign himself a fool and madman. Yet what strikes us is the composure of his spirit even in that danger: his heart was so fixed, trusting in God, that he penned this excellent psalm with all the marks of a calm, sedate spirit.
