Moses
Psalm 44:2BSB·traditional attribution

With Your hand You drove out the nations and planted our fathers there; You crushed the peoples and cast them out.

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

How thou didst drive out the heathen with thy hand. The destruction of the Canaanites from the promised land is the work here brought to remembrance. A people numerous, warlike, gigantic and courageous, firmly established and strongly fortified, were driven out by a far feebler nation, because the Lord was against them in the fight.

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.
