11:25 In the same way, he also took the cup after supper, saying, “This cup is the new covenant in my blood. Do this, every time you drink it, in remembrance of me.”

1 Corinthians 15:52

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.

[15:52]  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.
