John Calvin Commentary Matthew 20:34

"And Jesus, being moved with compassion, touched their eyes; and straightway they received their sight, and followed him." — Matthew 20:34 (ASV)

And followed him. This was an expression of gratitude⁶⁷³ when the blind men became followers of Christ; for, though it is uncertain how long they discharged this duty, yet it showed a grateful mind that they presented themselves to many on that journey as mirrors of the grace of Christ. Luke adds that the people gave praise to God, which tends to prove the certainty of the miracle.

⁶⁷³ “Ceci a este un signe de recognoissance du bien receu de Christ;” — “this was an expression of gratitude for the favor received from Christ.”;” — “this was an expression of gratitude for the favor received from Christ.”
