Everyone here has a write-up, drawn from the same records that explain the names while you read the text.
Joseph
Patriarch, ruler in EgyptJacob's favored son, sold into slavery by his brothers, imprisoned on a false accusation, and raised to second in Egypt because he could read dreams. When his brothers finally stood before him he said the line the whole story turns on: you meant it for evil, God meant it for good.
Genesis 37-50Exodus 1:5-8Deuteronomy 33:13-17
Joshua

Joshua 2Joshua 6:25Matthew 1:5
Balaam
Seer for hireA diviner from the Euphrates hired to curse Israel, who could only say what God gave him to say, including one of the clearest messianic lines in the Torah. The Bible's later verdict on him is harsh: Numbers, Peter, Jude, and Revelation all treat him as the pattern of a religious professional who sells his gift.
Numbers 22-24Numbers 31:16Deuteronomy 23:4-5
Achan
Who took the devoted thingsHe kept a robe, silver, and gold from Jericho when everything had been devoted to destruction, and hid them under his tent. Israel's next battle, against a tiny town, failed because of it, and the search narrowed tribe by tribe until it reached him.
