Charles Ellicott Commentary 2 Samuel 7:18

"Then David the king went in, and sat before Jehovah; and he said, Who am I, O Lord Jehovah, and what is my house, that thou hast brought me thus far?" — 2 Samuel 7:18 (ASV)

Then went king David in, and sat. — As always at every important point in his life, David’s first concern was to bring what was on his mind before the Lord. The place where he went must have been the tent he had pitched for the ark. Here he sat to meditate in God’s presence on the communication that had now been made to him, and then to offer his thanksgiving (2 Samuel 7:18–21), praise (2 Samuel 7:22–24), and prayer (2 Samuel 7:25–29).

The Divine Name is here printed with the word GOD in small capitals. This is always done in the Authorised Version wherever it stands for JEHOVAH in the original. The same custom is also followed with the word LORD. Out of reverence for the name, Jehovah never has its own vowels in Hebrew, but is printed with those belonging to Lord, or if this word is also used, then with those belonging to God.
