OET interlinear NUM 16:48

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

וַ⁠יַּעֲמֹ֥ד בֵּֽין־הַ⁠מֵּתִ֖ים וּ⁠בֵ֣ין הַֽ⁠חַיִּ֑ים

and,he_stood between the,dead and=between the,living

The implication is that Aaron positioned himself where he could stop the plague from spreading to the rest of the people. You could include this information if that would be helpful to your readers. Alternate translation: [And he stood where the plague was spreading, stationing himself between the people who were dying and the people who were still alive]

Note 2 topic: figures-of-speech / activepassive

וַ⁠תֵּעָצַ֖ר הַ⁠מַּגֵּפָֽה

and,it_was_restrained the,plague

The expression was restrained is a passive verbal form. If your language would not use that form, you could express the idea in active form or in another way that is natural in your language. If you need to say who does the action, the context indicates that it is God. Alternate translation: [And the plague stopped] or [And Yahweh restrained the plague]
