Vulg. 1 Kgs 1:51

Et nuntiaverunt Salomoni, dicentes: Ecce Adonias timens regem Salomonem, tenuit cornu altaris, dicens: Juret mihi rex Salomon hodie, quod non interficiat servum suum gladio.

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.
