John Gill Commentary Genesis 11:27

"Now these are the generations of Terah. Terah begat Abram, Nahor, and Haran. And Haran begat Lot." — Genesis 11:27 (ASV)

Now these are the generations of Terah
Or the genealogy of his posterity, which is a very short one; for it only gives an account of his three sons as before,

Terah begat Abram, Nahor, and Haran :
and of three grand children, Lot, Milcah, and Iscah, the children of Haran; and chiefly for the sake of Abram it is given, and indeed the above genealogy of Shem, which ends with him; and of whom and whose posterity the remaining part of this book of Genesis treats:

and Haran begat Lot :
of whom we have some further account in (Genesis 13:1–14:24) (19:1-38) .
