John Trapp on Psalms 112:4

Verſ. 4. Ʋnto the upright, there ariſeth light in darkneſs] i.e. Joy in tribulation, as did unto the Martyrs, plenty in penury, at having nothing, and yet poſſeſſing all things, 2. Cor, 6 10. If they have not an external affluence, yet they have an internal influence of grace and comfort, which is far better and ſweeter, I Tim. 6.6. Some render the words thus, He who is gracious, and full of compaſſion, and righteous (i.e. God) cauſeth light to ariſe in darkneſs upon the upright; who alſo, is, according to his meaſure, and by participation from God, gracious, merciful, and righteous.
