Obsequiousness in the Bible

1 Samuel 25:23-31 And when Abigail saw David, she hasted, and lighted off the ass, and fell before David on her face, and bowed herself to the ground, 24 And fell at his feet, and said, Upon me, my lord, upon me let this iniquity be: and let thine handmaid, I pray thee, speak in thine audience, and hear the words of thine handmaid. 25 Let not my lord, I pray thee, regard this man of Belial, even Nabal: for as his name is, so is he; Nabal is his name, and folly is with him: but I thine handmaid saw not the young men of my lord, whom thou didst send. 26 Now therefore, my lord, as the LORD liveth, and as thy soul liveth, seeing the LORD hath withholden thee from coming to shed blood, and from avenging thyself with thine own hand, now let thine enemies, and they that seek evil to my lord, be as Nabal. ...
1 Samuel 25:41 And she arose, and bowed herself on her face to the earth, and said, Behold, let thine handmaid be a servant to wash the feet of the servants of my lord.

2 Samuel 9:8 And he bowed himself, and said, What is thy servant, that thou shouldest look upon such a dead dog as I am?

2 Samuel 14:4-20 And when the woman of Tekoah spake to the king, she fell on her face to the ground, and did obeisance, and said, Help, O king. 5 And the king said unto her, What aileth thee? And she answered, I am indeed a widow woman, and mine husband is dead. 6 And thy handmaid had two sons, and they two strove together in the field, and there was none to part them, but the one smote the other, and slew him. 7 And, behold, the whole family is risen against thine handmaid, and they said, Deliver him that smote his brother, that we may kill him, for the life of his brother whom he slew; and we will destroy the heir also: and so they shall quench my coal which is left, and shall not leave to my husband neither name nor remainder upon the earth. ...
