Genesis 21:25

That the foundation of true friendship might be firmly laid, and the peace inviolably observed, he removes an impediment to it, an occasion of quarrel and just exception on Abraham's part. A well of water in those hot and dry countries was of great esteem and necessity. Compare Genesis 26:19 Judges 1:15. Besides, a well may be put for wells, as the Greeks render it, and as may seem probable by comparing this with Genesis 26:15,18; it being an ordinary thing to use the singular number for the plural, as hath been showed. See Genesis 3:2, Genesis 4:20.
