Kehillah in Corinth I 9:24-26

Orthodox Jewish Bible

²⁴ Do you not have da’as that the ones running on a race course all indeed run, but it is only one who receives the prize? So run that you may obtain the prize.

²⁵ And everyone competing in the [Olympic] games in all things exercises shlitah atzmi: those ones, therefore, that they may obtain a perishable wreath; but we, an imperishable.

²⁶ Therefore, I run not as one without a goal that is kovua (fixed, set). I box as not beating the air.
