26 And said, If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee.
27 And they came to Elim, where were twelve wells of water, and threescore and ten palm trees: and they encamped there by the waters.
Along with the tree that healed the bitter waters, God gave the Israelites a covenant that He would heal them and keep them from the plagues of Egypt, so long as they obeyed His commandments. This making of covenants out in the wilderness brings to mind a similar scene with their namesake, Jacob/Israel, after he had fled the home of his birth and was on his way to a new land. It seems being out in the wild, untethered from all prior patterns and support is an ideal place to establish new commitments with God. When an individual or a people are at their lowest and barest is when God can finally pour a new foundation in their heart.
I also want to draw attention to the different ways that Israel is commanded to follow God. They are to “hearken to the voice of the Lord,” then “do that which is right in his sight.” This is then repeated in another way as, “give ear to his commandments,” and then “keep all his statues.” Twice we are shown that the pattern for obeying is both listening/hearkening, as well as doing/keeping. There is an element of discovering God’s will, and an element of doing it. And make no mistake, it is His will. “Do that which is right in his sight,” was the command, not what is right in our sight, or according to our own biased interpretation of His will. None of us can do any good if it isn’t God’s good.
Then, after offering this covenant to Israel, God then gave them a great gift: twelve wells of water and seventy palm trees. A literal oasis in the desert, a flowing refuge from the thirst that had troubled them, a sign that God was more than equipped to care for their every need. If Israel would bring the faithful obedience, God would bring all the healing, life-sustaining waters.
