1 Chronicles 29:24 - Clarke's commentary and critical notes on the Bible

And all the princes, and the mighty men, and all the sons likewise of king David, submitted themselves unto Solomon the king. Submitted themselves - נתנו יד תחת שלמה nathenu yad tachath Shelomoh. "They gave the hand under Solomon;" they swore fealty to him. We have already seen that putting the hand under the thigh (super sectionem circumcisionis) was the form of taking an oath. See the note on Genesis 24:9.
