What did Abraham do at Beersheba in Genesis 21:33?
In Beersheba, Abraham planted a grove and called there on the name of the Lord, the everlasting God. The Hebrew word for everlasting is olam. Olam can mean from everlasting to everlasting, or it can mean hide or hideth, as used in some Psalms.
Les explains that in Genesis 21:33, while God is still dealing with Abraham in that place, Abraham planted a grove in Beersheba and called there on the name of the Lord, the everlasting God. The Hebrew word for everlasting is olam, which is another name of deity. Olam in regular usage can mean from everlasting to everlasting, which God is. But it can also mean hide or hideth, as seen when Psalms uses the same word and says, 'why hidest thou thyself from us?' This connects to the earlier point that Jesus could honestly tell the eleven it was not for them to know the day or hour.
And Abraham planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God.
