na.tar describes keeping watch over what is entrusted and retaining anger or a grudge.

The dominant attested use concerns watchful custody of vineyards and, in one clause, enemies; a second use concerns holding onto anger, a grudge, or hostile disposition rather than letting it cease.

1. Watchful custody of vineyards or enemies · dominant

   In Song of Songs 1:6, feminine singular participial forms occur where the woman is appointed keeper of a vineyard and says that she has not kept her own vineyard. In Song of Songs 8:11 and Song of Songs 8:12, masculine plural participles identify vineyard keepers; Nahum 1:2 uses a masculine singular participle in a clause the APB renders "keeps watch on his enemies."

2. Retaining anger or a grudge · common

   Leviticus 19:18 places the imperfect form alongside the prohibition of avenging and retaining a grudge against one's people. Jeremiah 3:5 and Psalm 103:9 ask or state whether anger will be kept forever, while Jeremiah 3:12 contrasts mercy with being angry forever.

In the Anselm Project Bible: The APB presents the participial vineyard contexts with "keeper" and "keepers," and Nahum 1:2 with "keeps watch." In the anger contexts it uses "keep a grudge," "keep anger," and "be angry"; These render the clauses rather than establish separate lexical definitions.
