Js 1:7-8 (King James)

⁷ Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper withersoever thou goest.
⁸ This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.

Js 1:7-8 (Vulgate)

⁷ Confortare igitur, et esto robustus valde, ut custodias, et facias omnem legem, quam præcepit tibi Moyses servus meus : ne declines ab ea ad dexteram vel ad sinistram, ut intelligas cuncta quæ agis.
⁸ Non recedat volumen legis hujus ab ore tuo : sed meditaberis in eo diebus ac noctibus, ut custodias et facias omnia quæ scripta sunt in eo : tunc diriges viam tuam, et intelliges eam.
