OET interlinear NUM 18:15

uW Translation Notes:

Note 1 topic: figures-of-speech / idiom

כָּל פֶּ֣טֶר רֶ֠חֶם

all/each/any/every first_offspring_of womb

Yahweh is using Every opener of the womb as a common expression of the culture to mean “every firstborn.” If this phrase does not have that meaning for your readers, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [Every firstborn child and animal]

Note 2 topic: figures-of-speech / reduplication

פָּדֹ֣ה תִפְדֶּ֗ה

to_redeem you_must_redeem

Yahweh is repeating forms of the verb redeem in order to intensify his expression of the idea that it conveys. If your language can repeat words for intensification, it would be appropriate to do that here in your translation. If not, your language may have another way of expressing the intensification. Alternate translation: [you shall surely redeem]
