'Diligently' in the Bible

and they say, 'A man, an Egyptian, hath delivered us out of the hand of the shepherds, and also hath diligently drawn for us, and watereth the flock;'

And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.

And now, if you will diligently listen to me and keep my covenant, then you will be my special possession out of all the nations, for all the earth is mine,

for, if thou diligently hearken to his voice, and hast done all that which I speak, then I have been at enmity with thine enemies, and have distressed those distressing thee.
