Equivalent to, “I would rather have you open idolaters than hypocrites, fancying you can worship Me and yet at the same time serve idols” (Amo 5:21, Amo 5:22, Amo 5:25, Amo 5:26; compare 1Ki 18:21; 2Ki 17:41; Mat 6:24; Rev 3:15, Rev 3:16).
Go ye, serve - This is not a command to serve idols, but a judicial declaration of God’s giving up of the half-idol, half-Jehovah worshippers to utter idolatry, if they will not serve Jehovah alone (Psa 81:12; Rev 22:11).
hereafter also - God anticipates the same apostasy afterwards, as now.
