A good old ancient hymn

Not so in haste, my heart!
Have faith in God, and wait;
Although He linger long,
He never comes too late.

He never comes too late;
He knoweth what is best;
Vex not thyself in vain;
Until He cometh, rest.

Until He cometh, rest.
Nor grudge the hours that roll;
That feet that wait for God
Are soonest at the goal.

Are soonest at the goal
That is not gained with speed;
Then hold thee still, my heart,
For I shall wait His lead.
