David
Psalm 44:4BSB·traditional attribution

You are my King, O God, who ordains victories for Jacob.

John Calvin Reformed @genevareformer

PSALM 44 This psalm is divided into three principal parts. In the beginning of it the faithful record the infinite mercy of God towards his people, and the many tokens by which he had testified his fatherly love towards them. Then they complain that they do not now find that God is favorable towards them, as he had formerly been towards their fathers.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Thou art my King, O God. Knowing right well thy power and grace my heart is glad to own thee for her sovereign prince. Who among the mighty are so illustrious as thou art? To whom, then, should I yield my homage or turn for aid? God of my fathers in the olden time, thou art my soul's monarch and liege Lord. Command deliverances for Jacob.

Matthew Henry Presbyterian @wholebiblehenry

Some observe that most of the psalms that are entitled Maschil - psalms of instruction, are sorrowful psalms; for afflictions give instructions, and sorrow of spirit opens the ear to them. Blessed is the man whom thou chastenest and teachest. In these verses the church, though now trampled upon, calls to remembrance the days of her triumph, of her triumph in God and over her enemies.
