Matthew Henry on Lamentations 3:21-36
Here the clouds begin to disperse and the sky to clear up; the complaint was very melancholy in the former part of the chapter, and yet here the tune is altered and the mourners in Zion begin to look a little pleasant. But for hope, the heart would break. To save the heart from being quite broken, here is something called to mind, which gives ground for hope (Lam 3:21), which refers to what comes after, not to what goes before. I make to return to my heart (so the margin words it); what we have had in our hearts, and have laid to our hearts, is sometimes as if it were quite lost and forgotten, till God by his grace make it return to our hearts, that it may be ready to us when we have occasio…
