18.2 & 7 repeated description of "Cush people."
19.11 Zoan (Old Egyptian: Sant= “stronghold,” the modern San). A city on the Tanitic branch of the Nile, called by the Greeks Tanis. It was built seven years after Hebron in Palestine (Num. 13:22). This great and important city was the capital of the Hyksos, or Shepherd kings, who ruled Egypt for more than 500 years. It was the frontier town of Goshen. Here Pharaoh was holding his court at the time of his various interviews with Moses and Aaron. "No trace of Zoan exists; Tanis was built over it, and city after city has been built over the ruins of that" (Harper, Bible and Modern Discovery). Extensive mounds of ruins, the wreck of the ancient city, now mark its site (Isa. 19:11, 13; 30:4; Ezek. 30:14). "The whole constitutes one of the grandest and oldest ruins in the world."
This city was also called “the Field of Zoan” (Ps. 78:12, 43) and “the Town of Rameses” (q.v.), because the oppressor rebuilt and embellished it, probably by the forced labor of the Hebrews, and made it his northern capital. http://christiananswers.net/dictionary/zoan.html?zoom_highlight=zoan
19.4, 12, 16, 17, 20, & 25 Lord of Hosts.
A name or title of God frequently used in the Old Testament, always translated "Yahweh of Hosts" (Yahweh tsebha'oth) in the American Standard Revised Version, since Yahweh, never 'Adhonay, is used in this phrase. Evidently the meaning of the title is that all created agencies and forces are under the leadership or dominion of Yahweh, who made and maintains them (Gen 2:1; Isa 45:12). It is used to express Yahweh's great power.

Joshua 5:14 will tell us that this man came as the “captain of the hosts of the Lord,” the commander of the Lord’s army. Joshua’s response in verse 14b and the statement of the captain in verse 15 show this was a theophany, or better, based on the truth of John 1:1-18, it was a Christophany. A Christophany is a manifestation of the preincarnate Christ, who, as the Logos, is the one who reveals God. If only a man or an angel, he would certainly have repelled Joshua’s worshipful response (vs. 14). Compare the response of Paul in Acts 14:8-20 to those who wanted to make them into gods and the response of the angel to John in Revelation 19:10.
Here then, the preincarnate Christ appears to Joshua to teach, guard, and reinforce certain vital truths for God’s people and especially for those in positions of leadership, which really includes all believers to some degree. J. Hampton Keathley III on Bible.org
