'Across' in the Bible

If, in the land which the Lord your God is giving you, you come across the dead body of a man in the open country, and you have no idea who has put him to death:

Do the same with his ass or his robe or anything which has gone from your brother's keeping and which you have come across: do not keep it to yourself.

For he came across her in the open country, and there was no one to come to the help of the virgin in answer to her cry.

And they are not across the sea, for you to say, Who will go over the sea for us and give us news of them so that we may do them?
