21:3 And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
21:17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.
2 Isaac is typical in fourfold way:
(1) of the Church as composed of the spiritual children of Abraham Galatians 4:28 .
(4) of the new nature of the believer as "born after the Spirit" Galatians 4:29 .
21:33 And Abraham planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God.
(See Scofield "Hebrews 1:4") .
(1) The Hebrew "Olam" is used in Scripture:
(b) an indefinite time or age Leviticus 25:32, "at any time"; Joshua 24:2 "in old time"). Hence the word is used to express the eternal duration of the being of God, Psalms 90:2 . "From everlasting to everlasting"), and is the Hebrew synonym of the Greek "aion," age or dispensation.
(See Scofield "Genesis 1:26") , note (4).
(2) The ideas therefore of things kept secret and of indefinite duration combine in this word. Both ideas inhere in the doctrine of the dispensations or ages. They are among the "mysteries" of God Ephesians 1:9 Ephesians 1:10 ; 3:2-6 ; Matthew 13:11 . The "everlasting" God (El Olam) is therefore that name of Deity in virtue of which He is the God whose wisdom has divided all time and eternity into the mystery of successive ages or dispensations. It is not merely that He is everlasting, but that He is God over everlasting things. See, for other names of Deity:
