do not throw away your confidence, which has a great reward

A person no longer having confidence is spoken of as if the person were to throw confidence away, like a person would discard something worthless. The abstract noun "confidence" can be translated with the adjective "confident" or the adverb "confidently." Alternate translation: "do not stop being confident, because you will receive a great reward for being confident" or "do not stop confidently trusting in God, who will reward you greatly" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-abstractnouns)
