1 Corinthians 9:25

9:25 Each competitor must exercise self-control in everything. They do it to receive a perishable crown, but we an imperishable one.

1 Corinthians 15:52-54

15:52 in a moment, in the blinking ¹  of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. 15:53 For this perishable body must put on the imperishable, and this mortal body must put on immortality. 15:54 Now when this perishable puts on the imperishable, and this mortal puts on immortality, then the saying that is written will happen,

“Death has been swallowed up in victory.” ² 

¹ tn The Greek word ῥιπή (rJiph) refers to a very rapid movement (BDAG 906 s.v.). This has traditionally been translated as “twinkling,” which implies an exceedingly fast – almost instantaneous – movement of the eyes, but this could be confusing to the modern reader since twinkling in modern English often suggests a faint, flashing light. In conjunction with the genitive ὀφθαλμοῦ (ofqalmou, “of an eye”), “blinking” is the best English equivalent (see, e.g., L&N 16.5), although it does not convey the exact speed implicit in the Greek term.
