What is an Asheirah?
Why does the Torah add the words "Kol Eitz"?
Rashbam: In order to forbid planting any tree in the vicinity of the Mizbe'ach - anywhere on the Har ha'Bayis. 1
Torah Temimah (citing Tamid, 25b): To teach us the prohibition against making wooden sun-porches in the Azarah.
Why does the Torah write "Lo Sita ... Asheirah" and not "Lo Sa'avod Asheirah" (See Sifsei Chachamim)?
Rashi: To render one Chayav already from the time of planting. 1
Rashi: Even if he does not worship it.
Why does the Torah juxtapose the Pasuk of Asheirah next to that of the judges?
Seforno: Refer to 16:19:4:4. Consequently, the Torah now presents three prohibitions which from a physical aspect, seem to enhance the Avodah, are forbidden because they are spiritually blemished: 1. - 'Asheirah', which beautifies the Mikdash, but is disgusting due to its attachment to Avodah-Zarah 1 ; 'Matzeivah,' which was favored before Matan Torah, 2 since it renders the person bringing the Korban as if he were standing before Hashem, 3 but fell out of favor after the episode with the Golden Calf, when they were no longer on that level. 4 3. 'A Ba'al-Mum', which may well improve the animal's appearance, but which is considered disgusting in he realm of Korbanos. 5
Targum Yonasan: To teach us that, just as one is forbidden to plant an Asheirah next to the Mizbe'ach of Hashem, so too, is it forbidden to include a fool (who is not conversant with Halachah) in the Beis-Din. 6
Seforno: See Mishpatim, Sh'mos, 24:4.

In similar fashion, in the following Pasuk, regarding the Isur of Matzeivos, Targum Yonasan explains comments that, just as it is forbidden to erect a Matzeivah, so too, is it forbidden to appoint a sinner as a communal leader - See Na'ar Yonasan - though it is unclear what prompts him to learn like that?
Why does the Torah prohibit planting an Asheirah specifically next to the Mizbe'ach?
