Diminutive, occurring only here in the Gospel, but repeatedly in the First Epistle. Nowhere else in the New Testament.
Now (ἀÌÏτι)
In Joh 13:31, now is νῦν, which marks the point of time absolutely. ἈÌÏτι marks the point of time as related to the past or to the future. Thus, “from the days of John the Baptist until now†(ἀÌÏτι, Mat 11:12). “Thinkest thou that I cannot now (ἀÌÏτι) pray to my Father?†though succor has been delayed all along till now (Mat 26:53). Here the word implies that the sorrowful announcement of Jesus' departure from His disciples had been withheld until the present. The time was now come.
