Joshua 18:18

18:18 It crossed to the slope in front of the Arabah to the north and descended into the Arabah.

Joshua 18:2

18:2 seven Israelite tribes had not been assigned their allotted land. ¹ 

Joshua 1:3-4

1:3 I am handing over to you every place you set foot, as I promised Moses. ²  1:4 Your territory will extend from the wilderness in the south to Lebanon in the north. It will extend all the way to the great River Euphrates in the east (including all of Syria) ³  and all the way to the Mediterranean Sea ⁴  in the west. ⁵ 

¹ tn Heb “there were left among the sons of Israel who had not divided up their inheritance seven tribes.”

² tn Heb “Every place on which the sole of your foot walks, to you I have given it, as I said to Moses.” The second person pronouns in vv. 3-4 are plural, indicating that all the people are addressed here. The verbal form נְתַתִּיו (nÿtattiv, “I have given it”) is probably a perfect of certitude, emphasizing the certainty of the action. Another option is to translate, “I have already assigned it.” In this case the verb would probably refer to the Lord’s decree to Abraham that he would give this land to his descendants.

³ tn Heb “all the land of the Hittites.” The expression “the land of the Hittites” does not refer to Anatolia (modern Turkey), where the ancient Hittite kingdom of the second millennium b.c. was located, but rather to Syria, the “Hatti land” mentioned in inscriptions of the first millennium b.c. (see HALOT 1:363). The phrase is omitted in the LXX and may be a scribal addition.

⁴ tn Heb “the Great Sea,” the typical designation for the Mediterranean Sea.

⁵ tn Heb “From the wilderness and this Lebanon even to the great river, the River Euphrates, all the land of the Hittites, even to the great sea [at] the place where the sun sets, your territory will be.”
