There are various theologies in Exodus. It means that many different theological thoughts support the theology of Exodus. It also suggests that we should find the coherent theological basis beneath those theologies. In this paper I mention five representative theologies: Theology of the Leader, Theology of Water and Land, Theology of Wilderness, Theology of Plagues, and Theology of Commandments. Moses shows that he is the true leader as well as the weak human. Also the concepts of water and land are intertwined throughout the texts of Exodus. Without the understanding of the relationship of the two it is almost impossible to appreciate the work of YHWH. On the way to the land of the promise, YHWH supplies water. It denotes that the harmony between water and land should be identified. Theology of plagues is the unique theological perspective in Exodus. Ten plagues are not only indispensible for Israel to come out of Egypt but also necessary steps to show who YHWH is to Pharaoh and the people of Egypt and Israel. After Israel"s exodus, the Israelites experience the life of the wilderness for 40 years. This period is to train Israel as the people of YHWH and also to convince them that YHWH is accompanying with them and showing His wonders to them. Last but not the least, I deal with Theology of Commandments. Due to the limit of space I only study the first and second commandment. Those two are the unique laws which are not found in any other nations in the Ancient Near East. Worshiping YHWH only and not making the image of YHWH should be understood within the specific milieu of Israel in history.
