John Gill Commentary Ezekiel 23:13

"And I saw that she was defiled; they both took one way." — Ezekiel 23:13 (ASV)

Then I saw that she was defiled
With idols, and the worship of them, (Ezekiel 23:7) : that they took both one way ;
the same way of idolatry; worshipped the same idols, lived the same course of life, were guilty of the same sin, both Israel and Judah.
