tach.ti describes what is situated beneath: especially the realm or land of descent, and also lower physical levels or places.

The term most often marks the realm or land reached by going down, associated in these verses with Sheol, the pit, death, and the slain. It also describes lower positions within physical arrangements and landscapes, including ark decks, water sources, and earthly depths.

1. The land or realm of descent · dominant

   In Ezekiel 32:18, the feminine plural form occurs as Egypt and other nations are sent down “to the land below” with those going down to the pit. The same setting recurs in Ezekiel 31:14, Ezekiel 31:16, Ezekiel 31:18, and Ezekiel 32:24, where death, descent, and the pit frame the location; Deuteronomy 32:22 and Psalm 86:13 likewise place it with Sheol.

2. Lower physical levels and locations · common

   In Genesis 6:16, the masculine plural form is part of the ark's sequence of “lower, second, and third decks.” Joshua 15:19 and Judges 1:15 distinguish upper water sources from lower ones, while Psalm 139:15 and Isaiah 44:23 use plural forms in phrases the APB renders “the depths of the earth.”

In the Anselm Project Bible: Across the supplied verses, the APB presents the term with expressions such as “land below,” “lower Sheol,” “lower decks,” “lower bowls,” and “depths of the earth.” These expressions indicate the verses' spatial presentation rather than fixed individual renderings.
