'Only begotten' in the Bible

Now, as he drew near unto the gate of the city, then lo! there was being brought forth, one dead, the only-begotten son of his mother, - and, she, was a widow; and, a considerable multitude of the city, was with her.

because he had, an only-begotten daughter, about twelve years old, and, she, was dying. Now, as he withdrew, the multitudes, were hemming him in.

And lo! a man from the multitude, uttered a cry, saying - Teacher! I beg of thee, to look upon my son, because, my only begotten, he is.
