1 Chronicles 16:38 explicitly calls Obed-edom a gatekeeper, confirming the role his sons inherit in this verse.

In 1 Chronicles 13:13, David leaves the ark at Obed-edom's house. This explains why God blessed him — the blessing came from hosting the ark.

1 Chronicles 15:18 mentions Obed-edom as a gatekeeper, consistent with his sons' listing here as gatekeeper families.

2 Samuel 6:10 records Obed-edom housing the ark, the event that brought his family into temple service as gatekeepers.
