And Laban called it. Each, in his own language, gives a name, of the same signification, to the heap. Whence it appears, that Laban used the Syrian tongue, though born of the race of Heber. But it is not wonderful that he, dwelling among Syrians, should have accustomed himself to the language as well as to the manners of the Syrians. And a little before, he is twice called a Syrian; as if Moses would describe him as degenerate, and alienated from the Hebrews. But this seems by no means accordant with the previous history, where we read that the daughters of Laban gave Hebrew names to their sons. Yet the solution is not difficult; for since the affinity between these languages was great, the inflection of one word into another was easy: besides, if the wives of Jacob were tractable, it is not surprising that they should have learned his language. And beyond doubt, he would himself make a point of this matter: seeing he knew that his family was separated from the rest of the nations. Moses, in using the name of Galeed, does it proleptically; for since he was writing for his own times, he does not scruple to give it the generally received name. Moreover we hence infer, that ceremonies and rites ought to refer to that which those who use them mutually agree upon. Which rule also ought to be applied to the sacraments; because if the word by which God enters into covenant with us be taken away, useless and dead figures will alone remain.
Laban called it Jegar-sahadutha - יגר שהדותא yegar sahadutha, the heap or round heap of witness; but Jacob called it גלעד galed, which signifies the same thing. The first is pure Chaldee, the second pure Hebrew. אגר agar signifies to collect, hence יגר yegar and אוגר ogar, a collection or heap made up of gathered stones; and hence also אגורא egora, an altar, used frequently by the Chaldee paraphrast. See 1-Kings 12:33; Judges 6:31; 2-Kings 21:3; Jeremiah 17:1. See Castel's Lexicon. From this example we may infer that the Chaldee language was nearly coequal with the Hebrew. A gloss made by St. Jerome, and which was probably only entered by him in his margin as a note, has crept into the text of the Vulgate. It is found in every copy of this version, and is as follows: Uterque juxta proprietatem linguae suae, Each according to the idiom of his own tongue.
And Laban called it Jegarsahadutha: but Jacob called it (k) Galeed.
(k) The one named the place in the Syrian tongue, and the other in the Hebrew tongue.
And Laban called it Jegarsahadutha,.... Which in the Syriac and Chaldee languages signifies "an heap of witness"; it being, as after observed, a witness of the covenant between Laban and Jacob:
but Jacob called it Galeed; which in the Hebrew tongue signifies the same, "an heap of witness"; or "an heap, the witness", for the same reason. Laban was a Syrian, as he sometimes is called, Genesis 25:20, wherefore he used the Syrian language; Jacob was a descendant of Abraham the Hebrew, and he used the Hebrew language; and both that their respective posterity might understand the meaning of the name; though these two are not so very different but Laban and Jacob could very well understand each other, as appears by their discourse together, these being but dialects of the same tongue.
