The Baal Peor episode (Num 25,1-18), followed by the second census (Num 26), marks the break between the first compromised wilderness generation and the second. This episode is a «covenant of kinship» between Israelites and Midianites resident in Moab, sealed by marriage between high-status individuals from each of these lineages. The violent repudiation of this transaction by the Aaronid Phineas is in marked contrast to the Midianite marriage of Moses, for which an explanation is offered, and is paradigmatic of the attitude to intermarriage of the Aaronid priesthood during the mid-to-late-Achaemenid period.
