And God command thee so. Jethro does not suppose that Moses will take his advice without further consultation. He assumes that the matter will be laid by Moses before God, and God's will learnt concerning it.
The entire narrative supposes that there was some established means by which the Israelite leader could refer a matter to Jehovah and obtain a decision upon it. This can scarcely have been as yet the Urim and Thummim.
Probably Moses held frequent communication with Jehovah by means of waking visions. Thou shalt be able to endure—i.e; "the work will not be too much for thee—thou wilt be able to bear it." This people shall also go to their place in peace.
The "place" intended would seem to be Palestine. Keil supposes that the word "peace" is to be taken literally, and concludes from it that breaches of the peace had previously been frequent, the people having "often taken the law into their own hands on account of the delay in the judicial decision;" but this is to extract from the words more than they naturally signify.
"In peace" means "cheerfully, contentedly." If the changes which he recommends are carried out, Jethro thinks that the people will make the rest of the journey to Canaan quietly and contentedly, without complaint or dissatisfaction.
