My parents were youth choir goers when I was little and they would sings this chorus, mostly mum.

Woi Mwathani Jehova tarora wone, ndingihota kwaria tondu nii ndi munini.

Jeremiah menya okoiga ati wimunini...ngugutwara kwi mundu o wothe...

Jeremiah 1:4-8New International Version (NIV)

The Call of Jeremiah

⁴ The word of the Lord came to me, saying,

⁵ “Before I formed you in the womb I knew^[a] you,
    before you were born I set you apart;
    I appointed you as a prophet to the nations.”

⁶ “Alas, Sovereign Lord,” I said, “I do not know how to speak; I am too young.”

⁷ But the Lord said to me, “Do not say, ‘I am too young.’ You must go to everyone I send you to and say whatever I command you. ⁸ Do not be afraid of them, for I am with you and will rescue you,” declares the Lord.

And this chorus:

On a riu maai no maruru
Kuuma micii nginya mawiraini
Kuuma ciana nginya andu agima
Nimaruru tukunywa ki?

Musa weruini githima kia maai
Maai marura makiaga kunywika
Kirindi giothe gikiuria Musa
Nimaruru, tukunywa ki?
