Ezekiel 8:14

Then he brought me to the door of the gate of the Lord’s house which was toward the north; and, behold, there sat women weeping for Tammuz.

Cross-reference

Ezekiel 8:6 introduces the abominations including Tammuz — showing the escalating pattern of idolatry.

Ezekiel 44:4 shows the same north gate later filled with God's glory — contrasting the Tammuz mourning here.

Ezekiel 11:12 rebukes Israel for following pagan nations — directly related to Tammuz worship here.

2 Kings 23:7 describes women weaving for Asherah in the temple — similar idolatrous women's rites, later cleansed by Josiah.
