申命记 1:46

ותשבו בקדש ימים רבים SO YE ABODE IN KADESH MANY DAYS — viz., nineteen years, as it is said here כימים אשר ישבתם, ACCORDING TO THE DAYS THAT YE ABODE, i.e. abode at all the other stations. They (the total years) were thirtyeight years; nineteen of them they spent at Kadesh, and nineteen years they went moving about aimlessly, and then they returned to Kadesh, as it is said, (Numbers 32:13) “And he made them move about in the wilderness”. — Thus have I found in Seder Olam 8.

וַתֵּשְׁב֥וּ בְקָדֵ֖שׁ יָמִ֣ים רַבִּ֑ים כַּיָּמִ֖ים אֲשֶׁ֥ר יְשַׁבְתֶּֽם׃

So you abode in Qadesh many days, according to the days that you abode there.
