The Lord who is just will cut the necks of sinners:

the Lord

Ezra 9:15 O Lord God of Israel, thou art just: for we remain yet to be saved as at this day. Behold we are before thee in our sin, for there can be no standing before thee in this matter.

Nehemiah 9:33 And thou art just in all things that have come upon us: because thou hast done truth, but we have done wickedly.

Lamentations 1:18 Sade. The Lord is just, for I have provoked his mouth to wrath: hear, I pray you, all ye people, and see my sorrow: my virgins, and my young men are gone into captivity.

Lamentations 3:22 Heth. The mercies of the Lord that we are not consumed: because his commiserations have not failed.

Daniel 9:7 To thee, O Lord, justice: but to us confusion of face, as at this day to the men of Juda, and to the inhabitants of Jerusalem, and to all Israel, to them that are near, and to them that are far off, in all the countries whither thou hast driven them, for their iniquities, by which they have sinned against thee.
