This may not be for everyone (it isn't for me), but for most people a billboard would be the correct answer.
use donkeys as their transportation while making expeditions into the countryside.
Egyptians gained wealth and land through heredity. They inherit the wealth and land that the previous generation accumulated and use the wealth and land to acquire some more. That would be another way, buying. More or less, it is not just the lands and wealth that are bought but the people that owned these. They are bought out for their service, buying their freedom to serve a more powerful being. Thus, acquiring their wealth and land and adding it unto their own. Another one is through conquering. There are small groups at places that are rich in wealth and land. When a man in power finds this, it is easily conquered and the wealth and land would also be acquired adding it to their own. Another one would be through discovery. Wealth or land with no ownership would result to a first-come-first-serve basis. When the first man owns it, it is up to him how to defend it from people who want the same thing. In the society, the royalty or the Pharaoh would be the wealthiest and the one with the most lands through the ways mentioned above.
