Midrasz do Jozuego 5:7

There are three afflictions, (namely,) the affliction of the fast, the affliction of the prison, and the affliction of the road. Whence do we know of the affliction of the fast? (Because it is said,) "I afflicted my soul with fasting" (Ps. 35:13). Whence do we know of the affliction of the prison? (Because it is said,) "They hurt his feet with fetters" (Ps. 105:18). Whence do we know of the affliction of the road? (Because it is said,) "He weakened my strength in the way" (Ps. 102:23). On account of the affliction of the road, (the children of Israel) did not circumcise, and when they went forth from Egypt all the people were circumcised, both young and old, as it is said, "For all the people that came out were circumcised" || (Josh. 5:5).
