dried plants that people grind into a powder and put in oil or food to give it a nice smell or flavor. See how you translated this in Exodus 25:6. (See: rc://en/ta/man/translate/translate-unknown)

"500 shekels ... two hundred and fifty shekels." A shekel is about 11 grams. Translators may use units that people know and round numbers: "5.7 kilograms ... 11.4 kilograms" or "six kilograms ... three kilograms" (See: rc://en/ta/man/translate/translate-numbers and rc://en/ta/man/translate/translate-bweight and rc://en/ta/man/translate/translate-fraction)

There were evidently shekels of more than one weight at the time. This specified which one was to be used. See how you translated this in Exodus 30:13. (See: rc://en/ta/man/translate/translate-bweight)

Translators may use units that people know and round numbers: "3.7 liters" or "four liters" (See: rc://en/ta/man/translate/translate-bvolume and rc://en/ta/man/translate/translate-fraction)

Possible meanings are 1) Moses was to have a perfumer do the work or 2) Moses was to do the work himself the way a perfumer would do it.
