Quick answer

God declared He would establish His covenant with Isaac, to be born to Sarah within a year. The promise is given a definite, near timetable.

Overview

God reaffirms that the covenant belongs to Isaac and fixes the time of his birth, removing all doubt about the promise's fulfillment. The appointed time underscores God's sovereign control over events. This precise promise heightens anticipation and demonstrates that the covenant rests wholly on God's faithful word, soon to be proven true.
