Esias 38:19 In-Context

17 For thou hast chosen my soul, that it should not perish: and thou hast cast all sins behind me.
18 For they that are in the grave shall not praise thee, neither shall the dead bless thee, neither shall they that are in Hades hope for thy mercy.
19 The living shall bless thee, as I also : for from this day shall I beget children, who shall declare thy righteousness,
20 O God of my salvation; and I will not cease blessing thee with the psaltery all the days of my life before the house of God.
21 Now Esaias had said to Ezekias; Take a cake of figs, and mash them, and apply them as a plaster, and thou shalt be well.
