Thus saith the mercy of the Lord,
"I'll be a God to thee;
I'll bless thy num'rous race, and they
Shall be a seed for me."

Abram believed the promised grace,
And gave his sons to God;
But water seals the blessing now,
That once was sealed with blood.

Thus Lydia sanctified her house,
When she received the word;
Thus the believing jailer gave
His household to the Lord.

Thus later saints, eternal King!
Thine ancient truth embrace;
To thee their infant offspring bring,
And humbly claim the grace.
