Moses
Deuteronomy 27:17BSB·traditional attribution

‘Cursed is he who moves his neighbor’s boundary stone.’ And let all the people 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 removeth his neighbour's landmark,.... Removes it backward, and steals ground, as Jarchi explains it; this is commonly done secretly; see Deu 19:14, and all the people shall say Amen; See Gill on Deu 27:15; See Gill on Deu 27:16.
