Deuteronomy 29:28

And cast them. In the Hebrew the word cast them ( יַשְׁלִכֵם ) has one of its letters, the ל , larger than the rest, and another letter, י which should be after the ל , is omitted; on which " Baal Hatturim noteth. There is a great lamed and a want of yod , to teach that there is no casting away like that of the ten tribes" (Ainsworth). According to Baxtorf, the large lamed represents the first letter of l'olam , forever, and the yod , the numeral 10, represents the ten tribes, whose perpetual omission from the nation of Israel is thus indicated.
