מַבְלִ֥יגִיתִ֖י עֲלֵ֣י יָג֑וֹן עָלַ֖י לִבִּ֥י דַוָּֽי׃
Though I would take comfort against sorrow, my heart is faint within me.
Rashi on Jeremiah
Were I to suppress my grief Heb. מבליגיתי, my suppression, and it is a noun, (mes estenimenc in O.F.). That is to say, if I said, I will suppress and keep in my grief.
Rashi on Jeremiah
my heart is sick within me From the voice of the prophecies that are revealed to me of the coming retributions.
