1 sn The first event of the Israelites’ desert experience is a failure, for they murmur against Yahweh and are given a stern warning – and the provision of sweet water. The event teaches that God is able to turn bitter water into sweet water for his people, and he promises to do such things if they obey. He can provide for them in the desert – he did not bring them into the desert to let them die. But there is a deeper level to this story – the healing of the water is incidental to the healing of the people, their lack of trust. The passage is arranged in a neat chiasm, starting with a journey (A), ending with the culmination of the journey (A'); developing to bitter water (B), resolving to sweet water (B'); complaints by the people (C), leading to to the instructions for the people (C'); and the central turning point is the wonder miracle (D).
2 tn The verb form is unusual; the normal expression is with the Qal, which expresses that they journeyed. But here the Hiphil is used to underscore that Moses caused them to journey – and he is following God. So the point is that God was leading Israel to the bitter water.
3 sn The mention that they travelled for three days into the desert is deliberately intended to recall Moses’ demand that they go three days into the wilderness to worship. Here, three days in, they find bitter water and complain – not worship.
