'Disbelieve' in the Bible

This precious value, then, is for you who believe [in Him as God’s only Son—the Source of salvation]; but for those who disbelieve,“The [very] stone which the builders rejectedHas become the chief Cornerstone,”

and,“A stone of stumbling and a rock of offense”; for they stumble because they disobey the word [of God], and to this they [who reject Him as Savior] were also appointed.
