“It came to pass.” Joshua 15:18 is worded exactly the same as Judges 1:14.

“arrived.” The Hebrew is an idiom: literally, “came to” him. In this context, it might mean, and some scholars think it means, to marry, thus, “came to in marriage,” but this is reading quite a bit into the text (cp. NLT, “when Acsah married Othniel”).
