John Trapp on Isaiah 22:22-23

Ver. 22. And the Key of the Houſe of David will I lay upon his ſhoulder] Rulers have their back-burdens.

Fructus honos oneris: fructus honoris onus.

The meaning is, he ſhall have chief authority under the King, together with dexterity and diſcretion to manage it aright. And herein Eliakim was a Type of Chriſt, Rev. 3.7. Let us pray for ſuch Eliakims as a common bleſſing.

Sit princeps miſeris paxillum, cui appendeant urceolos ſuos. Scult. Ver. 23. And I will faſten him as a nail] Paxilli ſimile & concinnum & amabile eſt. On a nail are hung Utenſils of the houſe: any ſuch thing as cannot ſtand by its own ſtrength. Eliakim was to be a common ſupport to the people; but eſpecially to his fathers houſe.

And he ſhall be for a glorious Throne] He ſhall enoble his whole ſtock and kindred.
