What does 1 Kings 1:51 mean?

And it was told Solomon, saying, Behold, Adonijah feareth king Solomon; for, lo, he hath laid hold on the horns of the altar, saying, Let king Solomon swear unto me first that he will not slay his servant with the sword.

And it was told Solomon, saying, Behold, Adonijah feareth king Solomon: for, lo, he hath caught hold on the horns of the altar, saying, Let king Solomon swear unto me to day that he will not slay his servant with the sword.

And it was told Solomon, saying, Behold, Adonijah feareth king Solomon; for, lo, he hath laid hold on the horns of the altar, saying, Let king Solomon swear unto me first that he will not slay his servant with the sword.

And they gave Solomon word of it, saying, See, Adonijah goes in such fear of King Solomon, that he has put his hands on the horns of the altar, saying, Let King Solomon first give me his oath that he will not put his servant to death with the sword.

And it is declared to Solomon, saying, `Lo, Adonijah feareth king Solomon, and lo, he hath laid hold on the horns of the altar, saying, Let king Solomon swear to me as to-day--he doth not put to death his servant by the sword.'

And they told Solomon, saying: Behold Adonias fearing king Solomon, hath taken hold of the horn of the altar, saying: Let king Solomon swear to me this day, that he will not kill his servant with the sword.

And it was told Solomon saying, Behold, Adonijah fears king Solomon; for behold, he has caught hold of the horns of the altar, saying, Let king Solomon swear to me this day that he will not put his servant to death with the sword.
