OET interlinear NUM 9:16

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

כֵּ֚ן יִהְיֶ֣ה תָמִ֔יד

yes/correct/thus/so will_belong continuously

The implication is that this situation with the cloud covering the tent in the daytime and appearing as fire at night continued throughout the entire time that the Israelites traveled in the wilderness. You could include this information if that would be helpful to your readers. Alternate translation: [So it is continually while the Israelites traveled through the wilderness]

Note 2 topic: figures-of-speech / explicit

וּ⁠מַרְאֵה־אֵ֖שׁ לָֽיְלָה

and=appearance fire night

By the appearance of fire is at night, the author means that the cloud that covered the sacred tent appeared like fire during the night. You could indicate this explicitly in your translation if that would be helpful to your readers. See how you translated the fuller expression of this idea in 9:15. Alternate translation: [and the cloud appeared like fire at night]
