What does Judges 13:24 mean?

Everything "the angel of the LORD" said to Manoah and his wife happens (Judges 13:2–14). This proves they were right to trust Him. They have a son, and Manoah's wife names him "Samson." In the Old Testament, both women and men are shown deciding the names of their children.

Scholars offer many possible explanations for this choice. Scripture, itself, gives no clear motives for selecting the name "Samson." The name is related to the word for "sun," meaning perhaps "little sun." Some commentators suggest this shows how enmeshed Israel's worship of the Lord was with that of other gods. Manoah and his wife lived close to Beth Shemesh, the center of worship for a solar cult. During this era, Yahweh may have sometimes also been depicted as the sun, perhaps borrowing from pagan cults. It could be that Samson's name was influenced by all of that. Or, it might have been a deliberate choice to defy such beliefs (Judges 6:32). We cannot say for sure.

Samson grew from baby to young man, and He was blessed by the Lord. Details are scarce in this part of his life. We're not told if this blessing took the form of unusually good health and strength, or financial blessings, or other happy circumstances. Samson will later be known for Holy Spirit-driven acts of supernatural strength (Judges 14:6, 19; 15:14–15; 16:3) but is not depicted as an obviously muscular person. The precise nature of these blessings, or how they appear, is not explained in the Bible.
