Hosea 10:1 shows the same pattern: increased prosperity leads to more altars, which become occasions for sin. Reinforces the irony.

Hosea 10:2 adds God's response: He will break down those altars because Israel's heart is false.

Hosea 10:8 depicts the altars destroyed and overgrown — the outcome of Ephraim's sin in building altars.

In Hosea 5:3, God declares He knows Ephraim's whoredom — the same unfaithfulness that leads to multiplying sin altars here.

Hosea 12:11 mentions altars at Gilgal as worthless stone heaps — echoes futility of Ephraim's multiplied altars for sin.
