Albert Barnes 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 ... - that is, that right hand so often stretched out to help now grasped a weapon ready for Judah’s destruction.

Were pleasant - Or, it was “pleasant.” Put a full stop after “eye.” Begin the third couplet thus:

In the tabernacle - (or, tent) of the daughter of Zion.
