Numbers 21:17-20

Verse 17

Spring up, O well, etc. - This is one of the most ancient war songs in the world, but is not easily understood, which is commonly the case with all very ancient compositions, especially the poetic. See the remarks Exo 15:1 (note), etc.
Verse 18

The princes digged the well - with their staves - This is not easily understood. Who can suppose that the princes dug this well with their staves? And is there any other idea conveyed by our translation? The word חפרו chapharu, which is translated they digged, should be rendered they searched out, which is a frequent meaning of the root; and במשענתם bemishanotham, which we render with their staves, should be translated on their borders or confines, from the root שען shaan, to lie along. With these corrections the whole song may be read thus: -

Spring up, O well! Answer ye to it.

The well, the princes searched it out.

The nobles of the people have digged it.

By a decree, upon their own borders

This is the whole of the quotation from what is called the book of the wars of the Lord. But see Dr. Kennicott's remarks at the end of this chapter.
