Charles Ellicott Commentary Lamentations 2:4

"He hath bent his bow like an enemy, he hath stood with his right hand as an adversary, And hath slain all that were pleasant to the eye: In the tent of the daughter of Zion he hath poured out his wrath like fire." — Lamentations 2:4 (ASV)

He stood with his right hand ... —The point of the phrase is that the “right hand,” the natural symbol of divine power, which had formerly been stretched out to protect, was now seen shooting the arrows and wielding the sword of vengeance.

Slew all that were pleasant ... —Better, “Destroyed all that was pleasant,” the destruction including not only warriors and youths, but everything dear and precious.

The tabernacle ... —Not the Temple, but the city itself as the habitation of the people, who are collectively represented as “the daughter of Zion.”
