Sparrow is the name given to various small seed-eating birds of the finch family. They are very common around the world, and can be somewhat useful to humans for their consumption of weed seeds. They tend to be very gregarious, living and nesting together in close flocks - sometimes 2 or 3 dozen nests will be constructed in or on the same tree or building. Their nests are built of natural materials such as grass and feathers, as well as various bits of human trash that they now find in the modern world, such as scraps of paper, string, and other things more potentially dangerous - sparrows have been known (very rarely) to cause building fires after a still-smoldering discarded cigarette was picked up and used in a nest.
Sparrows were well-known to the people of Bible History; sparrows and swallows were permitted to build their nests in the Temple (see Temples) in Jerusalem:
"How lovely is Thy dwelling place, O Lord of hosts! My soul longs, yea, faints for the courts of The Lord; my heart and flesh sing for joy to the living God. Even the sparrow finds a home, and the swallow a nest for herself, where she may lay her young, at Thy altars, O Lord of hosts, my King and my God. Blessed are those who dwell in Thy house [see "My Father's House"], ever singing Thy praise!" (Psalm 84:1-4 RSV)
Jesus Christ used sparrows in His warning about the persecution that was coming upon The Elect in that time, and the end time:
"When they deliver you up, do not be anxious how you are to speak or what you are to say; for what you are to say will be given to you in that hour; for it is not you who speak, but the Spirit of your Father speaking through you."
"Brother will deliver up brother to death, and the father his child, and children will rise against parents and have them put to death; and you will be hated by all for My Name's sake. But he who endures to the end will be saved. When they persecute you in one town, flee to the next; for truly, I say to you, you will not have gone through all the towns of Israel, before the Son of man comes."
"A disciple is not above his teacher, nor a servant above his master; it is enough for the disciple to be like his teacher, and the servant like his master. If they have called the master of the house Beelzebul, how much more will they malign those of his household."
"So have no fear of them; for nothing is covered that will not be revealed, or hidden that will not be known. What I tell you in the dark, utter in the light; and what you hear whispered, proclaim upon the housetops. And do not fear those who kill the body but cannot kill the soul; rather fear Him who can destroy both soul and body in hell. Are not two sparrows sold for a penny? And not one of them will fall to the ground without your Father's will. But even the hairs of your head are all numbered. Fear not, therefore; you are of more value than many sparrows."
"So every one who acknowledges Me before men, I also will acknowledge before My Father Who is in heaven; but whoever denies me before men, I also will deny before My Father Who is in heaven." (Matthew 10:19-33 RSV)
