11 And the ark of the Lord abode in the house of Obededom the Gethite three months: and the Lord blessed Obededom, and all his household.
Douay–Rheims · Challoner revision · 2 Kings 6:11
Why this matters
The Ark remains in Obededom’s house for three months, bringing blessing. Luke 1:56 records Mary’s stay for about three months. The duration is a concrete narrative parallel, read typologically in Catholic tradition.
