'Be Ready' in the Bible

But as for you, O house of Israel Thus, saith my Lord. Yahweh, Go. serve every man his own manufactured gods, Yet afterwards, surely Ye shall be ready to hearken unto me, - And my holy name, shall ye profane no more, With your gifts, and With your manufactured gods.

Be ready, and prepare {yourselves}, you and all of your assembly, the assembling around you, and you must be for them as a guard.
