Abraham had enough faith to leave his homeland and go into exile as a foreigner in a foreign land, even though he didn’t know where he was going (12:2). He had faith that Yehovah would give him descendants, and this faith made him righteous (15:6). However, he later doubted that God would give his descendants the land of Canaan (15:8) and asked for a sign (15:9). This shows us that faith pleases God, even though it may not be complete or perfect faith.
Abraham knew God’s name as twice in this portion he called on the name of Yehovah (12:8; 13:4). In casual dialogue with Melchizedek and the king of Sodom, he makes a point to use the proper name of God so that there is no confusion about in whom he trusts. Melchizedek blessed Abraham “by God Most High, Creator of heaven and earth” (14:19), while Abraham stated, “to Yehovah, God Most High, Creator of heaven and earth” (14:22).
God confirmed His promise of the land to Abraham by making a unilateral contract. God made a blood covenant with Abraham while he slept (15:17). This is explained later as an everlasting covenant (17:7). The borders of the Promised Land given to Israel are from the Nile to the Euphrates (15:18) and everywhere Abraham walked (13:17). As Israel has not yet possessed these borders, it is likely that this remains an unfulfilled prophecy, and that we can expect the Kingdom of God in the last days to fill this land.
Isaiah gave a prophecy of comfort to Israel. Israel had already suffered losses due to Assyrian aggression, and further losses to captivity were imminent. Isaiah described the last days when a way will be prepared for Yehovah’s kingdom (40:3). At that time, God will protect His people (40:11), and Jerusalem will preach the gospel of the Kingdom to all nations (40:9).
Yehovah stated that He is the first and the last (41:4).
