John Trapp on Isaiah 9:3

Ver. 3. Thou haſt multiplyed the Nation] Or, Never ſince thou multiplyedſt this people, didſt thou give them ſuch joy: i, e. ſuch matter of joy as now Thou intendeſt to do: Or thus, Thou wilt multiply this Nation: thou wilt encreaſe their joy; eſpecially by ſending thy Son, who is called the Gift, John 4.10. the Benefit, 1 Tim. 6.2. ſuch as wherein all diſcontents are ſoon ſwallowed up. Everlaſting Joy ſhall be upon the Heads of the Lords Ranſomed ones, they ſhall obtain joy and gladneſs, and ſorrow and ſighing ſhall flye away, Iſa. 35.10.

They joy before thee] Pleaſure there muſt be in the wayes of God, becauſe therein men let out their ſouls into God the Fountain of all good. Chriſts Chariot is paved with Love, Cant. 3.9, 10.

According to the joy in Harveſt] and a great deal more, Pſalm 4.7. They do over-abound exceedingly with joy, 2 Cor. 7.4. Joyes they have unſpeakable, and full of glory, 1 Pet. 1.8.

And as men rejoyce when they divide the ſpoil] Wherein the pleaſure is uſually more then the profit, Pſal. 119.162. and yet the profit oft very great too, as 2 Chron. 20.25. and as at the ſack of Conſtantinople, at the wealth whereof the Turks themſelves wondered, and derided their folly, that poſſeſſing ſo much they would beſtow ſo little in the defence of themſelves and their Countrey. Turk Hiſt. fol. 345.
