2 Samuel 7:18

David … sat before the Lord. The word "sat" is usually explained by commentators as meaning "tarried." The rabbins give the word its ordinary meaning, and say that it was the privilege of kings to pray in a sitting posture. But we cannot possibly believe that kings at this early stage had established a special etiquette for observance in prayer, and the difficulty is merely imaginary. Because the Jews prayed standing, and we moderns pray kneeling, we both assume that to pray sitting was an irreverent act. It was not so, nor are we to think of David as sitting at ease in a chair. He sat upon the ground, as was the Oriental custom, with his feet doubled under him, and his head bent forward; and in this posture meditated upon Jehovah's message, and then poured out his thoughts. As it is expressly said that "he sat before Jehovah," the place must have been the outer court of the tabernacle. Who am I, O Lord Jehovah! In the Authorized Version Jehovah is rendered "God," because it has the vowels of the word Elohim; usually it is rendered "Lord," because the Masserites attached to it the vowels of Adonai, "lord," equivalent to Dominus. As Adonai here precedes Jehovah, the Massorites were driven from their usual practice, and were so superstitious as to suppose it more reverent to pronounce the name Elohim than that of Jehovah, to which the Jews attached magical powers. David's words are not so much a prayer as a meditation, full of thanksgiving, and even of wonder at the greatness of God's mercies to him. In it he first acknowledges his own unworthiness and the meanness of his father's house compared with the high dignity which God is bestowing upon him. For not only has he raised him to the kingly office, but promised him the continuance of his house "for a great while to come." Whether David understood as yet that he was now placed in the same position as Abraham of old, in that "in his seed all the families of the earth should be blessed," is uncertain, and depends upon the interpretation put upon the following words. This only we may affirm, that whet he says in this place of his house remaining until a distant future falls far short of the meaning of the passages quoted above from the Psalms.
