Charles Ellicott Commentary Lamentations 1:10

"The adversary hath spread out his hand upon all her pleasant things: For she hath seen that the nations are entered into her sanctuary, Concerning whom thou didst command that they should not enter into thine assembly." — Lamentations 1:10 (ASV)

Upon all her pleasant things ... —The use of a similar phrase in 2 Chronicles 36:10; 2 Chronicles 36:19, of the vessels of the Temple, leads us to think primarily of them; but the word itself has a wider range, and includes all works of art and ornamentation.

Whom you commanded. —Stress is laid on the profanation rather than the plunder of the sanctuary. Ammonites and Moabites were excluded from the congregation in Deuteronomy 23:3, and yet they and other heathen nations now rushed even into the Holy of Holies, which only the High Priest might enter.
