Verse 29: And (Josh. 19:47) they called the name of the city (Gen. 14:14; Judg. 20:1; 1 Kings 12:29, 30; 15:20) Dan, after the name of Dan their father, who was born unto Israel: howbeit the name of the city was Laish at the first.
After the name of Dan their father; that it might be manifest that they belonged to the tribe of Dan, though they were seated at a great distance from them, even in the most northerly part of the land; whereas the lot of their tribe was in the southern part of Canaan.
[Which was called Laish before, וְאוּלָ֛ם לַ֥יִשׁ שֵׁם־הָעִ֖יר] And indeed (certainly [Jonathan], but [Munster, Syriac], although [Tigurinus], moreover [Arabic]) Laish was the name of the city (Montanus, Pagnine). But the Septuagint has, Ulam Laish, that is, the porch of Laish. We had a similar thing in Genesis 28:19, in which place see what things were said (Grotius). It was called לַיִשׁ/Laish, leonine, as it were; either, because it was mighty and very powerful; or, because that region was abounding in lions: which is not surprising, since it was near Libanus (Malvenda).
 Hebrew: וַיִּקְרְא֤וּ שֵׁם־הָעִיר֙ דָּ֔ן בְּשֵׁם֙ דָּ֣ן אֲבִיהֶ֔ם אֲשֶׁ֥ר יוּלַּ֖ד לְיִשְׂרָאֵ֑ל וְאוּלָ֛ם לַ֥יִשׁ שֵׁם־הָעִ֖יר לָרִאשֹׁנָֽה׃
 אוּלָם/ulam functions as an adversative adverb.
 Genesis 28:19: “And he called the name of that place Beth-el: but the name of that city was called Luz at the first (וְאוּלָ֛ם ל֥וּז שֵׁם־הָעִ֖יר לָרִאשֹׁנָֽה׃).”
 לַיִשׁ signifies lion.
