Malbim: At the same time that Melech Ashur took Hoshe'a ben Elah and incarcerated him, he took also the calf.
When will it be taken to Ashur?
Rashi (from Seder Olam 22): It was in the 12th year of Achaz - "va'Ya'ar Elokei Yisrael Es Ru'ach Pul Melech Ashur... va'Yaglem la'Reuveni..." (Divrei ha'Yamim I, 5:26), and he took the calves in Beis Kel, to fulfill "Gam Oso l'Ashur Yuval." Radak - Yuval is like "Yuval Shai" (Yeshayah 18:7).

Malbim: He took the calf, which is the shame of Efrayim.
What counsel is shame for Yisrael?
Rashi: The counsel to make the calves - "va'Yiva'etz ha'Melech va'Ya'as Shnei Eglei Zahav" (Melachim I, 12:28).
Malbim: The counsel to rebel against Hoshe'a and hand him over to Ashur. They thought that this will return Avodas ha'Egel. This caused the Egel to cease totally!
