Isaías 63

Isaías 63:14

"Like cattle that go down into the valley, the Spirit of the Lord gave them rest. So you did lead your people." Through all these words that the prophet speaks about the exodus of the Israelites from Egypt, he leads the mind back to the wonders that God performed by means of his servant Moses, whom he called the shepherd of his flock, and through whose right hand, which moved the staff, he divided the sea. The staff, therefore, prefigured the cross of Christ, who is the hidden arm of the glory of the Father. — COMMENTARY ON ISAIAH 63:14
