Nehemiah 9:2 reports the same separation from foreigners and confession — a parallel event earlier in the restoration.

Nehemiah 10:28 mentions those who separated from neighboring peoples for the Law — directly echoing the action in Nehemiah 13:3.

Ezra 10:11 commands separation from foreign peoples and wives — the same principle of purification applied earlier.

Ezra 9:1 reports the failure to separate from foreign peoples — the very problem that Nehemiah 13:3 addresses by enforcing separation.

In Ezra 9:2, the same problem of mixing with foreign peoples through marriage is described, providing background for the separation in Nehemiah.

In Ezra 10:8, sanctions against those who fail to address foreign marriages show a similar community-wide purification effort.
