And they entered into a covenant
 Asa and all his people; that is, as Piscator remarks, they went between the pieces of the calf cut asunder, for the confirmation of the covenant, see ( Jeremiah 34:18 ) , 
 to seek the Lord God of their fathers, with all their heart, and with
 all their soul;
 to serve and worship him most truly, sincerely, and cordially.
