The greater part of this psalm is occupied with meditations, in which David encourages himself and others to hope in God, and fortifies his mind against the assaults of temptation. And as we are ever prone to be drawn away from God by the influence which worldly objects exert over our senses, perishing and evanescent as these are, occasion is taken to show the folly of this, and bring us to a single and entire dependence upon God.
To the chief musician upon Jeduthun, A Psalm of David.
The fact being ascertained that there was one of the chief singers who bore the name of Jeduthun, some have thought that this psalm was committed into his hands to be sung, (1 Chronicles 9:16; 16:38, 41; and 25:1.) In the title to Psalm 39, it is sufficiently probable that the allusion is to some musician of that family. But this would not seem to be the case here; for the psalm is not said to be given to, but upon Jeduthun. This has led to the opinion that it formed the beginning of some song commonly known at that time. Still the Hebrew particle
1 Jeduthun was first chosen to be one of the chief musicians in conducting the praises of the Jewish sanctuary when the ark was brought from Obed-edom to mount Zion. His sons were also appointed to preside over different departments of the vocal and instrumental worship in the tabernacle. He had six sons who were thus employed. Jeduthun and his family appear to have been eminent for their piety, and to have been endued with the spirit of prophecy.
