'Preserve' in the Bible

come, we cause our father to drink wine, and lie with him, and preserve from our father -- a seed.'

And it cometh to pass, on the morrow, that the first-born saith unto the younger, 'Lo, I have lain yesterday-night with my father: we cause him to drink wine also to-night, and go thou in, lie with him, and we preserve from our father -- a seed.'

and now, be not grieved, nor let it be displeasing in your eyes that ye sold me hither, for to preserve life hath God sent me before you.
