'Matter' in the Bible

And he had commanded him concerning this matter not to go after other gods, but he did not keep that which Yahweh commanded.

This matter became sin in the house of Jeroboam, to make it disappear and to destroy [it] from the surface of the earth.

because David did right in the eyes of Yahweh and he didn't turn aside from all that he commanded him all the days of his life, except in the matter of Uriah the Hittite.
