ta.phach describes extending the heavens and an action associated with those reared and brought up in lament.

The clearest attested use describes the extending of the heavens in Isaiah 48:13; Lamentations 2:22 places the verb in the statement about those the speaker had “reared and brought up,” though the translation does not isolate the term’s contribution.

1. Extending the heavens · common

   In Isaiah 48:13, the Piel perfect third feminine singular form occurs in the statement about the speaker's right hand and the heavens; the APB renders the clause “my right hand extended the heavens.”

   Isaiah 48:13
2. Action toward those brought up · common

   In Lamentations 2:22, the Piel perfect first common singular form appears in the speaker's statement concerning those affected by the enemy; the APB renders the surrounding clause “whom I had reared and brought up.” The verb's precise contribution within that paired wording remains uncertain.

   Lamentations 2:22

In the Anselm Project Bible: The APB explicitly uses “extended” in Isaiah 48:13. In Lamentations 2:22 it gives “reared and brought up” for the surrounding clause, but its whole-verse wording does not identify a single English equivalent for the term.
