Rashi: It is an expression of [making] Shemamah (desolate).

Radak: She said "Esnah Hemah Li". She said that her grain, wine and oil and all her good are from her lovers. I will make them desolate, and she will know if the good was from Me or from them. Grapes and figs are the best human foods, after grain, and it already said "v'Lakachti Degani b'Ito ¹ " (11).

Malbim: Not only will He withhold the land's produce ? He will also make the land itself desolate, and the choicest fruit bearing trees, i.e. vines and fig trees. She said that they are Esnan that her lovers gave to her. She attributes also inheritance of the land to the Ba'alim (idolatry), like a Zonah who is brazen to say that the Nedunya that her husband gave to her [when he married her] is an Esnan that she received from her lovers. Therefore, I will make desolate the trees that bear fruits.

Rashi: This is like Esnan (a harlot's wage). Radak ? because she is compared to a Zonah, the good is called Esnan. This is like Tenai; the root is Tenah, and the Aleph is extra.

Radak citing Targum Yonasan: It is dear.

Rashi: Chayos go there and eat the Peros.

Radak: The enemy is compared to Chayas ha'Sadeh. Malbim ? wild nations that Sancheriv stationed there will eat the Peros.

Malbim (according to the Nimshal): After she said that she will return to her first husband, i.e. she began to repent in the days of Hoshe'a ben Elah, who removed the guards that Malchei Yisrael stationed to stop people from ascending to Yerushalayim for the festivals. Hashem saw that their Teshuvah is not complete, and their heart still leans to idolatry, just they thought that Mazal opposes them. Therefore he brought Melech Ashur against them and destroyed their land, and strangers dispossessed them.
