Deuteronomy 27:18ESV·traditional attribution

“‘Cursed be anyone who misleads a blind man on the road.’ And all the people shall say, ‘Amen.’

Matthew Henry Presbyterian @wholebiblehenry

When the law was written, to be seen and read by all men, the sanctions of it were to be published, which, to complete the solemnity of their covenanting with God, they were deliberately to declare their approbation of. This they were before directed to do (Deu 11:29, Deu 11:30), and therefore the appointment here begins somewhat abruptly, Deu 27:12.

John Gill Reformed Baptist @doctorgill

Cursed be he that maketh the blind to wander out of the way,.... By directing him wrong knowingly, or laying a stumbling block in his way, Lev 19:14. The Targum of Jonathan is,"that maketh a traveller wander out of the way, who like a blind man;''who knows his way no more than a blind man does.

Geneva Bible Notes Reformed @genevanotes

Cursed [be] he that maketh the blind to wander out of the way. And all the people shall say, Amen. (l) Meaning, that does not help and counsel his neighbour.
