Parallel
2 Kings 18:12
Brenton's English Septuagint · Berean Standard Bible
because they hearkened not to the voice of the Lord their God, and transgressed his covenant, [even] in all things that Moses the servant of the Lord commanded, and hearkened not [to them], nor did [them].
This happened because they did not listen to the voice of the LORD their God, but violated His covenant—all that Moses the servant of the LORD had commanded—and would neither listen nor obey.
