And though at first my conscience did grudge, To breake the boundes of friendship knit by oth, Yet after proofe (see mischiefe) I did iudge It madnes for a king to keepe his troth, And semblably with all the world it goth: Sinnes oft assayde are thought to bee no sinne, So soyleth sinne the soule it sinketh in. 17. But as diseases common cause of death, Bring daunger most when least they pricke and smart, Which is a signe they haue expulst the breath Of liuely heate, which doth defend the heart: Euen so such sinnes as felt are on no part Haue conquered grace, and by theyr wicked vre So kild the soule, that it can haue no cure. 18. And grace agate, vice still succedeth vice, And all to haste the vengeaunce for the furst, I areade therefore all people to bee wise, And stop the brake when it begins to burst: Attast no poyson (vice is venim worst, It mates the minde) beware eke of too much, All kill through muchnes, some with onely touch. 19. When I had learnde to set my oth at nought, And through much vse the sence of sinne exiled, Against king _Henry_ what I could, I wrought, My fayth, my oth, vniustly foule defiled:[665] And while slye fortune at my doings smyled, The wrath of God, which I had well deserued, Fell on my necke, for thus loe was I serued. 20. Ere I had raygned fully fifteene yeare, While time I lay at _Pertho_, at my place, With the queene my wife and children mee to chare, My murdring uncle with the double face, That longed for my kingdome and my mace, To slay mee there suborned _Robert Grame_, With whom his nephue, _Robert Stuard_, came. 21. And when theyr time fit for theyr[666] purpose founde, Into my priuy chamber they astart, Where with theyr swordes they gaue mee many a wound, And slue all such as stuck vnto my part: There loe my wife did shew her louing heart, Who, to defend mee, felled one or twayne, And was sore wounded ere I coulde bee slayne.[667] 22. See _Baldwine_, _Baldwine_, the vnhappy endes Of such as passe not for theyr lawfull oth: Of those that causeles leaue theyr fayth and[668] frendes, And murder kinsfolkes through their foes vntroth: Warne, warne all princes, all like sinnes to loth, And chiefly such as in my realme be borne, For God hates highly all that[669] are forsworne.][670]
