Jeremiah 31:39

And the measuring line shall yet go forth over against it upon the hill Gareb, and shall compass about to Goath.

The measuring line - (Ezekiel 40:8; Zechariah 2:1).

Gareb - from a Hebrew root [gaarab], to scrape; Syriac, leprosy: the locality outside the city where lepers were removed to.

Goath - from a root [ gaawa` (H1478)] to lose one's breath with toil, to toil, referring to the toilsome ascent there: outside of the city of David, toward the southwest, as Gareb was northwest (Junius).
