כִּ֭י אִם־יֵ֣שׁ אַחֲרִ֑ית וְ֝תִקְוָתְךָ֗ לֹ֣א תִכָּרֵֽת׃
Porque deveras terás uma recompensa; não será malograda a tua esperança.
Rashi on Proverbs
for because of this, there is a future Heb. כי אם. This [word] אם is used as an expression of “that”; i.e., for because of this there is a future and hope for you.
