It was the advice of the Rev. Samuel Clarke and other friends which encouraged Matthew Henry to begin writing a commentary on the whole Bible.
The following entry in his journal announced the commencement of the work:
'November 12 1704. This night, after many thoughts of heart, and many prayers concerning it, I began my Notes on the Old Testament. It is not likely I shall live to finish it, or if I should, that it should be of public service, for I am not par negotio; yet in the strength of God, and I hope with a single eye to his glory, I set about it, that I may endeavour something and spend my time to some good purpose and let the Lord make what use he pleaseth of me. I go about it with fear and trembling, lest I exercise myself in things too high for me. The Lord help me to set about it with great humility.'
