Charles Spurgeon Commentary Luke 17:15

"And one of them, when he saw that he was healed, turned back, with a loud voice glorifying God;" — Luke 17:15 (ASV)

Turned back, and with a loud voice glorified God.

This was a sure sign that he was healed, that he had his voice back; the disease had so thoroughly gone that the sound, which seemed to hide away in his husky throat, now came out clear and loud, like the stroke of a bell.

And one of them, when he saw that he was healed,

They all saw that they were healed, and they all must have felt extremely glad. Oh, the happiness of feeling the hot blood cooled, and full health taking the place of weakness and disease!
