Moses dwelt in the land of Midian 40 years and was about 83 years old when God spoke to him out of the Burning Bush. A more interesting movie would have been done if they had depicted Moses as 80 years old confronting Pharoah. Now Ben Kingsley did a version of Moses where he kept the stutter of Moses.(I am halt of speech).
God is always doing the opposite of what one would expect to prove his glory...giving Abraham a son when Abraham was 100 years old. Causing a virgin to conceive. Using an 80 year old man to free a nation. Using a single superhumanly strong man to destroy a philistine civilization in a single blow; while in its infancy, it could have grown to alter history and destroy Israel while becoming a force to rival future Rome.
you left out Gideon with 300 and a young shepherd boy with a slingshot slaying a 9’ giant.
