Parallel
Exodus 2:11
Brenton's English Septuagint · Berean Standard Bible
And it came to pass in that length of time, that Moses having grown, went out to his brethren the sons of Israel: and having noticed their distress, he sees an Egyptian smiting a certain Hebrew of his brethren the children of Israel.
One day, after Moses had grown up, he went out to his own people (note: Or his brothers) and observed their hard labor. He saw an Egyptian beating a Hebrew, one of his own people.
