Vous avez cherché: they live on forever in your heart (Anglais - Latin)

in your heart
custodi in corde tuo

what is in your heart for me?
quid enim mihi est cor tuum,

keep serenity in your heart and soul
corde et animo

face darkness with the light in your heart
absque timore inimicos tuos coram

live in peace and always in your hearts
sit cor eius in pace

and the star rises in your hearts
et lucifer oriatur in cordibus vestris

speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the lord;
loquentes vobismet ipsis in psalmis et hymnis et canticis spiritalibus cantantes et psallentes in cordibus vestris domin

therefore shall ye lay up these my words in your heart and in your soul, and bind them for a sign upon your hand, that they may be as frontlets between your eyes.
ponite haec verba mea in cordibus et in animis vestris et suspendite ea pro signo in manibus et inter vestros oculos conlocat

and jesus knowing their thoughts said, wherefore think ye evil in your hearts?
et cum vidisset iesus cogitationes eorum dixit ut quid cogitatis mala in cordibus vestri

settle it therefore in your hearts, not to meditate before what ye shall answer:
ponite ergo in cordibus vestris non praemeditari quemadmodum respondeati

and immediately when jesus perceived in his spirit that they so reasoned within themselves, he said unto them, why reason ye these things in your hearts?
quo statim cognito iesus spiritu suo quia sic cogitarent intra se dicit illis quid ista cogitatis in cordibus vestri

and he said unto them, why are ye troubled? and why do thoughts arise in your hearts?
et dixit eis quid turbati estis et cogitationes ascendunt in corda vestr

but sanctify the lord god in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:
dominum autem christum sanctificate in cordibus vestris parati semper ad satisfactionem omni poscenti vos rationem de ea quae in vobis est sp

and let none of you imagine evil in your hearts against his neighbour; and love no false oath: for all these are things that i hate, saith the lord.
et unusquisque malum contra amicum suum ne cogitetis in cordibus vestris et iuramentum mendax ne diligatis omnia enim haec sunt quae odi dicit dominu

for ye dissembled in your hearts, when ye sent me unto the lord your god, saying, pray for us unto the lord our god; and according unto all that the lord our god shall say, so declare unto us, and we will do it.
quia decepistis animas vestras vos enim misistis me ad dominum deum nostrum dicentes ora pro nobis ad dominum deum nostrum et iuxta omnia quaecumque dixerit tibi dominus deus noster sic adnuntia nobis et faciemu
