to.tsa.ah denotes the points where a boundary reaches or ends, and in Proverbs describes what proceeds from the heart into life.

The term most often marks the terminal points or reaches of territorial boundaries, including their arrival at seas, rivers, cities, or named locations. In Proverbs 4:23, the same construct-plural form occurs in the statement that life proceeds from the heart, extending the observed usage beyond mapped borders.

1. Boundary endpoints and reaches · dominant

   The construct plural occurs with a border or boundary as its associated element. In Numbers 34:5 the APB renders the clause "its outgoings shall be at the sea," while Joshua 18:14 has the border's reach at Kiriath-baal; Ezekiel 48:30 applies the plural to the city's "exits" on its north side.

2. What proceeds into life · rare

   In Proverbs 4:23, the construct plural stands in the clause "from it are the outgoings of life," following the instruction to watch the heart. The verse presents life as proceeding from the heart; the APB wording confirms the clause's overall direction.

   Proverbs 4:23

In the Anselm Project Bible: Across boundary passages, the APB variously uses "outgoings," "extremities," "end," and "exits"; Proverbs 4:23 also has "outgoings of life." These are verse-level renderings rather than definitions.
