Genesis 31:17

Then Jacob rose up
And went with them to Laban's house, where his children were, as is plain from Rachel's theft, ( Genesis 31:19 ) : and set his sons and his wives upon camels;
which were his own, see ( Genesis 30:43 ) ; creatures fit for travelling; on these he set his wives, Rachel and Leah, and his concubine wives, Bilhah and Zilpah; for these went with him, as appears from ( Genesis 33:6 ) ( 35:22 ) ; and "his sons", or rather "his children": for they were not all sons, there was one daughter, and they were all young; his eldest son Reuben could not be much more than twelve years of age, and his youngest son Joseph about six.
