But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.
God fixed a definite time for Sarah to bear Isaac, at the set time in the next year. He declared that He would establish His covenant with Isaac. The promise that Abraham would have many descendants was therefore to be fulfilled through Isaac, not through Ishmael.
