Matthew Poole and continuators on James 5:13

13 Is any among you afflicted ? let him pray . Is any merry? let him sing psalms.

Either troubled or afflicted in Mind, as appears by the opposite being merry, or more generally afflicted any way: Not that we need not Pray at other times, but when under Afflictions God calls us more especially to it, and our own necessities put us upon it.

For Support, Patience, Sanctification of Afflictions, &c.

Express his Mirth in an holy manner, by praising God with Psalms or Spiritual Songs for Mercies received from him, 1 Cor. 14.15. Eph. 5.19. and so keep up his spiritual mirth by a spiritual exercise, lest his cheerfulness degenerate into vanity and frothiness.
