Jamieson, Fausset & Brown, on Lam 2:2

“Beth. The Lord hath cast down headlong, and hath not spared, all that was beautiful in Jacob: he hath destroyed in his wrath the strong holds of the virgin of Juda, and brought them down to the ground: he hath made the kingdom unclean, and the princes thereof.”

“polluted--by delivering it into the hands of the profane foe. Compare Psa 89:39, "profaned . . . crown."”
