And they that know thy name - All who are acquainted with thee; all those who have been made acquainted with the manifestations of thy goodness, and with the truth respecting thy character.
Will put their trust in thee - That is, all who have any just views of God, or who understand his real character, will confide in him. This is as much as to say, that he has a character which is worthy of confidence - since they who know him best most unreservedly rely on him. It is the same as saying that all the revelations of his character in his word and works are such as to make it proper to confide in him. The more intimate our knowledge of God, the more entirely shall we trust in him; the more we learn of his real character, the more shall we see that he is worthy of universal love. It is much to say of anyone that the more he is known the more he will be loved; and in saying this of God, it is but saying that one reason why men do not confide in him is that they do not understand his real character.
For thou, Lord, hast not forsaken them that seek thee - Thou hast never left them when they have come to time with a confiding heart. David means, doubtless, to refer here particularly to his own case, to derive a conclusion from his particular case in regard to the general character of God. But what is here affirmed is still true, and always has been true, and always will be true, that God does not forsake those who put their trust in him. Men forsake him; he does not forsake them.
