The Lord my pasture shall prepare,
And feed me with a shepherd's care;
His presence shall my wants supply,
And guard me with a watchful eye.
Oh, when a mother meets on high
The babe she lost in infancy,
Hath she not then for pains and fears,
The day of woe, the watchful night,
For all her sorrow, all her tears,
An over-payment of delight?
