And he did not many mighty works there because of their unbelief. And he did not many mighty works there because of their unbelief - Δυναμεις, miracles. So the word is used, Matthew 7:22; Matthew 11:20; Acts 19:11; 1 Corinthians 12:28; Galatians 3:5; Hebrews 2:4. The Septuagint translates נפלאות אל niphleoth el, the miraculous works of God, by δυναμιν κυριε.
Unbelief and contempt drive Christ out of the heart, as they did out of his own country. Faith seems to put the almighty power of God into the hands of men; whereas unbelief appears to tie up even the hands of the Almighty. A man, generally speaking, can do but little good among his relatives, because it is difficult for them to look with the eyes of faith upon one whom they have been accustomed to behold with the eyes of the flesh. - Quesnel.
