Psalms 31:24

Be of good courage, and he shall strengthen your heart - In 1 Corinthians 16:13, St. Paul says, "Watch ye, stand fast in the faith; quit you like men; be strong:" Γρηγορειτε, στηκετε εν τῃ πιστει, ανδριζεσθε, κραταιουσθε. The latter words he seems to have borrowed from the Septuagint, who translate, "Be of good courage, and he shall strengthen your heart," by Ανδριζεσθε και κραταιουσθω ἡ καρδια ὑμων "Act like men, and your hearts shall be strengthened." They that hope in God, and are endeavoring to walk carefully before him, may take courage at all times, and expect the fullness of the blessing of the Gospel of peace.

Be of good courage - See a similar exhortation at the close of a psalm, in Psalm 27:14. Compare the notes at that verse. As the result of all his own experience of the goodness of God, and of His gracious interposition in the time of danger, the psalmist exhorts others to be encouraged, and to feel assured that God would not leave or forsake them.

And he shall strengthen your heart - He will animate you; he will enable you to meet trial and opposition; he will keep you from becoming faint and disheartened.

All ye that hope in the Lord - All that put their trust in him, or all whose expectation is from him. It is a characteristic of true piety that all hope centers in God, or that the soul feels that there is no other ground of hope.

(a) The truly pious man despairs of success in anything else, or from any other quarter, for he feels that God alone can give success.

(b) He does hope in God - in reference to all that is needful for himself as an individual; all that will be for the good of his family; all that will tend to bless the world; all that he desires in heaven. Hope in God cheers him, sustains him, comforts him; makes life happy and prosperous; and makes death calm, serene, triumphant.
