Numbers 4:6

4:6 Then they must put over it a covering of fine leather and spread over that a cloth entirely of blue, and then they must insert its poles.

Numbers 8:16

8:16 For they are entirely given to me from among the Israelites. I have taken them for myself instead of all who open the womb, the firstborn sons of all the Israelites.

tn The exact meaning of the Hebrew word here is difficult to determine. The term תַּחַשׁ (takhash) has been translated “badgers’ [skins]” by KJV. ASV has “sealskin” while RSV uses “goatskin”; NEB and NASB have “porpoise skin,” and NIV has “hides of sea cows.” This is close to “porpoise,” and seems influenced by the Arabic. The evidence is not strong for any of these meanings, and some of the suggestions would be problematic. It is possible the word is simply used for “fine leather,” based on the Egyptian ths. This has been followed by NRSV (“fine leather”) and NLT (“fine goatskin leather”) along with the present translation. See further HALOT 1720-21 s.v. תַּחַשׁ.

tn As before, the emphasis is obtained by repeating the passive participle: “given, given to me.”

tn Or “as substitutes” for all the firstborn of the Israelites.
