“And moreover I have heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered My covenant.” – Exodus 6:5
A covenant was made with Abraham, many years before his descendants entered Egypt: “And He said unto Abram: ‘Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years” (Genesis 15:12-13, JPS 1917 Tanach).
H’Shem sent Moshe, whom He spoke to at the burning bush: “‘I have surely seen the affliction of My people that are in Egypt, and have heard their cry by reason of their taskmasters; for I know their pains; and I am come down to deliver them out of the hand of the Egyptians.” (Exodus 3:7-8).
For H’Shem heard the cry of His people; he “descended to rescue them from the hand of the Egyptians” (Exodus 3:8, Complete Jewish Bible, chabad.org). Such is His love for His children, that he “descended to rescue them.” Even though, He is thought of in Talmudic thought as sitting on His throne in Seventh Heaven, He heard our cries from there.
The Talmud further explains that He can even hear the penitent whisper prayers in the synagogue: for He is not only transcendent; He is also immanent. This explains to some degree how He can be the Master of the Universe, as well as the One who effects miracles to release His people from bondage.
