Rashi: If you find a liar who prophesizes to them that they will profit in wine and strong drink, this nation will accept him for a Navi.

Radak: This returns to what they told Hashem's Nevi'im not to prophesize. In contrast, if a man's ways are folly and Sheker, and he tells them 'you will have Shalom; do as your hearts desire' (refer to 2:11:2:1).

Malbim: If I would send to you a false Navi, who tells you lies or matters based on his straying imagination, that you will be drunkards, and he would tell them "Asof E'esof Yakov Kulech" (12), and this false Navi says in My name 'I will gather Yakov from where they are dispersed' ? good Nevu'os and consolations.

Radak: He says, 'if you will give to me wine or strong drink, I will prophesize nice Nevu'os for you.' They desire his words and listen, and he is a Navi for them.
