30:4 ascended up into heaven. The answer to the seven rhetorical questions in these verses can be none other than God Himself, together with His Son. The Lord Jesus gave the answer to the first two questions one thousand years later, in his conversation with Nicodemus (John 3:13).
30:4 what is His name. Agur was certainly familiar with the name of God as Creator (that is, Elohim—see verse 5) and His name as the eternally existing one (that is, Jehovah—see Proverbs 30:9), but he did not know the name associated with having a Son. It is noteworthy that the Hebrew word for father, ab, occurs over five hundred times in the Old Testament, but never in addressing God in prayer, not even in the many prayers in the books of Psalms. Yet, when He came into the world, He taught us to address God as “Our Father” (e.g., Matthew 6:9). When Christ Himself prayed, especially in His hour of greatest stress, He prayed “Abba, Father” (Mark 14:36). A reasonable answer to Agur’s question, therefore, is that the name of God in relation to the Son is simply “Ab,” or “Abba,” the Aramaic equivalent. Unlike the ancient Israelites, we now feel very comfortable in addressing God as “Father”—or even as “Abba, Father” (Romans 8:15; Galatians 4:6).
30:4 his son’s name. Here is strong Old Testament evidence that the God of creation has a Son, by whom, in fact, He formed the winds and the waters and all the ends of the earth, and who finally descended from heaven to become the Son of man as well as Son of God. That Son’s name was given later through the prophet Isaiah—“Wonderful, Counsellor, The Mighty God, The Everlasting Father, The Prince of Peace” (Isaiah 9:6).
