Genesis 21

Verses 1-34

Returned unto the land of the Philistines. - Beer-sheba was on the borders of the land of the Philistines. Going therefore to Gerar, they returned into that land. In the transactions with Hagar and with Abimelek, the name God is employed, because the relation of the Supreme Being with these parties is more general or less intimate than with the heir of promise. The same name, however, is used in reference to Abraham and Sarah, who stand in a twofold relation to him as the Eternal Potentate, and the Author of being and blessing. Hence, the chapter begins and ends with Yahweh, the proper name of God in communion with man. “Eshel is a field under tillage” in the Septuagint, and a tree in Onkelos. It is therefore well translated a grove in the King James Version, though it is rendered “the tamarisk” by many. The planting of a grove implies that Abraham now felt he had a resting-place in the land, in consequence of his treaty with Abimelek. He calls upon the name of the Lord with the significant surname of the God of perpetuity, the eternal, unchangeable God. This marks him as the “sure and able” performer of his promise, as the everlasting vindicator of the faith of treaties, and as the infallible source of the believer’s rest and peace. Accordingly, Abraham sojourned in the land of the Philistines many days.
