The ark of God remained with Obed-edom’s family in his house for three months, and the Lord blessed his family and all that he had.

three years of famine, or three months of devastation by your foes with the sword of your enemy overtaking you, or three days of the sword of the Lord—a plague on the land, the angel of the Lord bringing destruction to the whole territory of Israel.’ Now decide what answer I should take back to the One who sent me.”
