1 Chronicles 28:6,7

He shall build my house, &c. So was he a figure of him that was to come, who is both the founder and the foundation of the gospel temple. I will establish his kingdom for ever This was to have its accomplishment in the kingdom of the Messiah which shall continue in his hands through all the ages of time, (Isaiah 9:7; Luke 1:33,) and shall then be delivered up to God, even the Father, with whom, however, he shall continue to reign to all eternity. If he be constant to do my commandments The promise is absolute with regard to the Messiah, but conditional with regard to Solomon. As at this day As he hath begun, and hitherto continued to do, in some good measure. If we are constant in our duty, then, and not otherwise, we may expect the continuance of his favour.
