Parallel
Isaiah 22:9
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἀνακαλύψουσιν τὰ κρυπτὰ τῶν οἴκων τῆς ἄκρας Δαυιδ καὶ εἴδοσαν ὅτι πλείους εἰσὶν καὶ ὅτι ἀπέστρεψαν τὸ ὕδωρ τῆς ἀρχαίας κολυμβήθρας εἰς τὴν πόλιν
You saw that there were many breaches in the walls of the City of David. You collected water from the lower pool.
