I don't think this is a will either, but a bond for £500.
A rough translation is
May all know by [these] presents we Robert
Parkinson of Blindhouse in Blearsdale in [the parish?] [of Lancashire]
and John Holt of Thirnam in the [county?] and [diocese?][?] and
Thomas Pennington of the same # # # #
to be held and firmly obliged to give [

??]by free
surrender and [

] in five hundred pounds of good and legal
money ####### of Great Britain the payer of the same giving to [?[ or
his certain attorney executors Administrators successors or
assigns making whatever payment well and faithfully
we oblige ourselves and [each?] of our heirs executors and
administrators firmly by [these] presents with our seals sealed dated
twenty fifth day of February Anno Domini 1723
Sorry, but I can't make out to whom the money was due, and I have made guesses in places, but I think this is the gist of it. Maybe it was owed to the person who had made the will?
Can anyone give a second and better informed opinion

Hope my effort helps anyway.

Correction: Not dated March but February. Have changed post.
