Antiquities of the Jews

Chapter 3.

THAT MOSES KINDLY RECEIVED-HIS FATHER-IN-LAW, JETHRO, WHEN HE CAME TO HIM TO MOUNT SINAI. FJAJ 3.17

NOW when Raguel, Moses's father-in-law, understood in what a prosperous condition his affairs were, he willingly came to meet him
And Moses and his children, and pleased himself with his coming
And when he had offered sacrifice, he made a feast for the multitude, near the Bush he had formerly seen; which multitude, every one according to their families, partook of the feast
But Aaron and his family took Raguel, and sung hymns to God, as to Him who had been the author procurer of their deliverance and their freedom
They also praised their conductor, as him by whose virtue it was that all things had succeeded with them
Raguel also, in his eucharistical oration to Moses, made great encomiums upon the whole multitude; and he could not but admire Moses for his fortitude, and that humanity he had shewn in the delivery of his friends. FJAJ 3.18
