'Unreservedly' in the Bible

except Caleb, the son of Jephunneh; he himself shall see it, and to him I will give the land upon which he has trodden and to his sons because {he followed Yahweh unreservedly}.'

Still, on some points I have written to you very boldly and without reservation to remind you [about them] again, because of the grace that was given to me from God,

Do not be over-anxious about anything, but by prayer and earnest pleading, together with thanksgiving, let your request be unreservedly made known in the presence of God.
