As in, let us.

As in, let my and let thine.

As in…

Let my cry come near before thee, O Lord:
give me understanding according to thy word.

Let my supplications come before thee:
deliver me according to thy word.

Let thine hand help me;
for I have chosen thy precepts.

Let my soul live,
and it shall praise thee;
and let thy judgments help me.

Psalm 119:169-176
