1 Chronicles 26:5

Ammiel the sixth, Issachar the seventh, Peulthai the eighth: for God blessed him.

Ammiel was Obed-edom's sixth son, Issachar his seventh, and Peulthai his eighth. God blessed Obed-edom. That blessing is evidence of the blessings that accompany God's law, which was represented by the ark kept in his home.
