Moses
Psalm 94:6BSB·traditional attribution

They kill the widow and the foreigner; they murder the fatherless.

This speaks terror enough to them, that they have the prayers of God's people against them, who cry day and night to him to avenge them of their adversaries; and shall he not avenge them speedily? Luk 18:3, Luk 18:7. Observe here, 1.
