And the sons of Asher; Jimnah, and Ishuah, and Isui, and Beriah, and Serah their sister: and the sons of Beriah; Heber, and Malchiel.
The sons of Asher - Ishuah, Isui. It accords with Oriental taste to have such rhyming names in families (cf. Genesis 22:21).
The sons of Beriah - Heber and Malchiel; not 'were' Heber and Malchiel; and hence, it is probable that they had been born in Canaan. These grandsons of Asher are enumerated here, because they appear as heads of families (Numbers 26:45).
