Yahweh is specifically requested to involve Himself in the problems that oppress His servants:
"How long wilt Thou forget me, O Lord! for ever? how long wilt Thou hide Thy face from me? How long shall I take counsel in my soul, having sorrow in my heart daily? how long shall mine enemy be exalted
over me?" (Ps. 13:1-2).
