How can Genesis 22:17 says "greatly multiply your seed" relate with Galatians 3:16 states "his seed" as in "one" (Jesus Christ))?
It seems to me that Genesis 22:17-18 uses seed to represent the Israelites people.
Genesis 22:17-18 New American Standard Bible (NASB)
17 indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens and as the sand which is on the seashore; and your seed shall possess the gate of their enemies. 18 In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.”
Galatians 3:16 New American Standard Bible (NASB)
16 Now the promises were spoken to Abraham and to his seed. He does not say, “And to seeds,” as referring to many, but rather to one, “And to your seed,” that is, Christ.
Therefore, Does Genesis 22:17 says "greatly multiply your seed" contradict Galatians 3:16 states "his seed" as in "one" (Jesus Christ))?
