Deuteronomy 27:14

“And the Levites shall speak, and say unto all the men of Israel, etc.] Rather, “answer f494 and say”; not the whole tribe of Levi, for that stood on Mount Gerizim to bless, (<052712>Deuteronomy 27:12); but the priests of that tribe who were placed in the valley, between the two mountains, and pronounced both the blessings and the curses in the hearing of all the tribes of Israel, to which they were to answer Amen; and that they might plainly hear, they expressed their words with a loud voice, clearly and distinctly, as follow.”

“Compare Joshua 8:32-35. The solemnity was apparently designed only for the single occasion on which it actually took place. Deuteronomy 27:12, Deuteronomy 27:13 The tribes appointed to stand on Gerizim to bless the people all sprang from the two wives of Jacob, Leah and Rachel. All the four tribes which sprang from the handmaids Zilpah and Bilhah are located on Ebal.

The transaction presents itself as a solemn renewal…”

“27:14 The Levites as a group were stationed on Mount Gerizim (27:12). The Ark of the Covenant accompanied them, and they offered sacrifices (Josh 8:30-35). It was part of the Levites’ role to teach and proclaim the Torah (Deut 33:10; see study note on 6:8; see also Lev 10:11).”

“Deu 33:9, Deu 33:10; Jos 8:33; Neh 8:7, Neh 8:8; Dan 9:11; Mal 2:7-9 Deuteronomy 27:15”

“"And the Levites shall lift up and speak to all the men of Israel with a high (loud) voice:" i.e., they shall pronounce the different formularies of blessing and cursing, turning towards the tribes to whom these utterances apply; and all the men of Israel shall answer "Amen," to take to themselves the blessing and the curse, as uttered by them; just as in the case of the priestly blessing in Num 5:22, and in connection with every oath, in which the person swearing took upon himself the oath that was pronounced, by replying "Amen." "The Levites" are not all the members of the tribe of Levi, but those "in whom the spiritual character of Levi was most decidedly manifested" (Baumgarten), i.e.,…”
