Note to A Midsummer's Night Dream, 3.2.86-87: "Which now in some slight measure it will pay, / If for his tender here I make some stay."
Which now in some slight measure it will pay, / If for his tender here I make some stay: i.e., to a small extent I will be able to "pay back" and hence find some relief from sorrow, if I pause here a while (make some stay) while sleep "tenders" or offers itself by way of paying the debt owed to sorrow, until sleep offers itself (in payment of that deficit).
