חֲב֧וּר עֲצַבִּ֛ים אֶפְרָ֖יִם הַֽנַּֽח־לֽוֹ׃
Ефрем присоединился к идолам; Оставь его в покое.
Rashi on Hosea
Ephraim is joined to idols [he] is joined to idols and cannot divest himself of them. Hence you, the prophet, ‘let him alone,’ and do not prophesy for the purpose of rebuking him since it will not avail.
