Matthew Poole and continuators on Genesis 48:6

6 And thy issue which thou begettest after them shall be thine , and shall be called after the name of their brethren in their inheritance .

Shall be reputed as thy children, and my grandchildren, and shall not have any distinct share, in my present or future inheritance, but shall have a part of their brethrens lot in such manner and proportion as thou shalt think fit, or as their succeeding Parents or Governours shall determine. But it doth not appear; nor doth Scripture any where mention, that Ioseph had any other sons but these, and therefore it is probable he had no more: onely Iacob speaks this upon supposition, in case he should have any other.

Either Ephraimites or Manassites.
