Verse 16. Adam - The city Adam being more obscure, is described by its nearness to a more known place, then eminent, but now unknown. The meaning is, that the waters were stopped in their course at that place, and so kept at a distance from the Israelites whilst they passed over. Against Jericho - Here God carried them over, because this part was,
1. The strongest, as having in its neighbourhood an eminent city, a potent king, and a stout and war-like people.
2. The most pleasant and fruitful, and therefore more convenient both for the refreshment of the Israelites after their long and tedious marches, and for their encouragement.
Verse 17. Stood firm - That is, in one and the same place and posture; their feet neither moved by any waters moving in upon them, nor sinking into any mire, which one might think was at the bottom of the river. And this may be opposed to their standing on the bank of the water when they came to it, commanded, ver. 8, which was but for a while, 'till the waters were divided and gone away; and then they were to go farther, even into the midst of Jordan, where they are to stand constantly and fixedly, as this Hebrew word signifies, until all were passed over. The midst of Jordan - In the middle and deepest part of the river.
