Reply To: Living in Eretz Yisroel

When it comes to the oaths, the Vayoel Moshe proofs its severity from the punishment of the Bnei Elhraim leaving 30 years before the time where 200,000 were slaughtered by the Philistines. See the Targum Yanoson in the beginning of Parashas Beshalach for not leading tne Bnei Yisroel tbe shorter way.
