Help needed deciphering portions of a probate clause 1633

[Zacktyr]

Hi, Rootschatters,

I have encountered three short phrases in a probate clause of 1633 that I need assistance with.  I have attached a screen short of the complete clause and have highlighted in yellow the three areas I need help with.

Thanking all of you for any assistance.
