신명기 2:14의 주석

והימים אשר הלכנו מקדש ברנע, from the place from which the spies had been sent out, 38 years had elapsed, seeing that the spies had been sent out in the second year after the Exodus.

V. 14. אנשי המלחמה, diejenigen, welche zur Zeit der Kundschaftersendung das kriegsfähige Alter hatten, die demzufolge bei der damals bereits beabsichtigten Besitznahme des Landes hätten tätig sein sollen, aus gottvergessenem Kleinmut jedoch vor dieser Aufgabe zurückgeschreckt waren.

והימים אשר הלכנו מקדש ברנע, “and the number o years it took us to walk from Kadesh barnea to the river Zered were 38 years.” Not all of these years were spent walking, of course, but the total period including the encampments was 38 years, until the last of the men of military ages at the time of the Exodus had died. The reason why the river Zered is named here is that it was the first of several rivers the Israelites crossed on their march north.
