John Gill Commentary Genesis 31:17

"Then Jacob rose up, and set his sons and his wives upon the camels;" — Genesis 31:17 (ASV)

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.
