What kind of promises does Israel have?
Israel's promises are earthly, not heavenly. From the promise to Abraham onward, Israel was a special, called-out, separated, covenant people, and all their promises pertain to the earth. They are God's earthly people, and even in resurrection as believers they remain earthly rather than heavenly.
Les explains that when Abraham was called out of Ur of the Chaldees, God separated him from the mainstream of humanity and promised that from that one man would come a distinctive race and nation, Israel. From the outset of the promise to Abraham until Israel was dispersed after rejecting their king, they were constantly taught they were a special, called-out, separated, covenant people of God. Les emphasizes that all Israel's promises are earthly, so they are called God's earthly people. He clarifies that Old Testament saints who died went to paradise, not to their eternal abode in heaven; when Jews experience resurrection as believers, they will not be a heavenly people but an earthly people. Even in their life in the flesh, all of Israel's promises were earthly, which explains why many had tremendous wealth, like Abraham.
