And they that know thy name will put their trust in thee: for thou, LORD, hast not forsaken them that seek thee.
And they that know thy name will put their trust in thee. They that know experimentally thy character in its past manifestations of love and power in their behalf will put their trust in thee for the time to come.
For (such know personally that) thou, Lord, hast not forsaken them that seek thee - therefore in confidence they will "seek" and "trust" in thee again.
