What does Genesis 38:11 mean?

Then said Judah to Tamar his daughter-in-law, Remain a widow in thy father’s house, till Shelah my son be grown up; for he said, Lest he also die, like his brethren. And Tamar went and dwelt in her father’s house.

Then said Judah to Tamar his daughter in law, Remain a widow at thy father’s house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brethren did. And Tamar went and dwelt in her father’s house.

Then said Judah to Tamar his daughter-in-law, Remain a widow in thy father’s house, till Shelah my son be grown up; for he said, Lest he also die, like his brethren. And Tamar went and dwelt in her father’s house.

Then Judah said to Tamar, his daughter-in-law, Go back to your father's house and keep yourself as a widow till my son Shelah becomes a man: for he had in his mind the thought that death might come to him as it had come to his brothers. So Tamar went back to her father's house.

And Judah saith to Tamar his daughter-in-law, `Abide a widow at thy father's house, till Shelah my son groweth up;' for he said, `Lest he die--even he--like his brethren;' and Tamar goeth and dwelleth at her father's house.

Wherefore Juda said to Thamar his daughter-in-law: Remain a widow in thy father's house, till Sela my son grow up: for he was afraid lest he also might die, as his brethren did. She went her way, and dwelt in her father's house.

And Judah said to Tamar his daughter-in-law, Remain a widow in thy father's house, until Shelah my son is grown; for he said, Lest he die also, as his brethren. And Tamar went and remained in her father's house.
