פעל ישב הועתק מענין הישיבה אל כל דבר המתעכב והנח על ענין אחד. (תזריע ס' טו, וסימן כ. אמור ס' רד, וסימן רה)
Ayelet Hashachar, translated by Betzalel Avraham Feinstein, 2021
The verb ישב (continue) is taken from the topic of ישיבה (dwelling) to talk about anything that is placed in one state and lingers there.
