Adam Clarke on Genesis 31:51

And Laban said to Jacob - behold this pillar, which I have cast betwixt me and thee - But this pillar, not cast but set up, was certainly set up by Jacob; for in Gen 31:45 we read, And Jacob took a stone, and set it up for a pillar: it is therefore for the honor of one Hebrew and one Samaritan MS. that they have preserved the true reading in Gen 31:51, ירית yaritha, Thou hast set up - Kennicott. Instead of either of the above readings the Samaritan text has yarata, The pillar which thou Seest betwixt me and thee.
