BEersheba] A place distant from Hebron (where Jacob now dwelt) about eight Germane miles: that is, of our English miles thirtie two: it was the ready way from Egypt to Canaan, and the utmost part of the Land of Canaan Southward toward Egypt. The word Beersheba, signifieth the well of the oath, or swearing: whereof see Annot. on Chap. 21. vers. 31. Here Abraham and Isaac had dwelled a long time, where they had built Altars, and offered sacrifices to God many times; and here doth Jacob offer sacrifice unto him, by way of thankfulnesse for former mercies, and of supplication for further favour in his journey. It is good to have recourse unto God, which way soever we take our course in the world.
the God of his father Isaac] Whereby he signified that he worshipped the true God, and also that he kept in his heart the possession of the Land, from whence present necessitie drove him; and he calleth him the God of his father Isaac, rather then of Abraham, (though he were his God also) because he learned to know him, and serve him by his father, and not by his grandfather. See Annot. on Chap. 31. vers. 42.
