Radak citing his father: "Ba'Midbar" is like "u'Midbarech Navah" (your speech is beautiful).
Why does it say "Elokim ha'Adirim" (plural)?

Malbim: Refer to 4:8:1:2.
I do not know why he said 'other'. Perhaps he means, any god other than the one they revere. Elokim is sometimes plural in Tanach, e.g. "Elokim Chayim" (17:26, Devarim 5:23. - PF)
