To cross one's fingers is a hand gesture commonly used to wish for luck. Occasionally it is interpreted as an attempt to implore God for protection. The gesture is referred to by the common expressions "cross your fingers", "keep your fingers crossed", or just "fingers crossed". The act of crossing one's fingers mainly belongs to Christianity. The earliest use of the gesture had two people crossing their index fingers to form a cross.
One can express crossed fingers in textual communication using U+1F91E 🤞 HAND WITH INDEX AND MIDDLE FINGERS CROSSED (HTML
🤞). This symbol was approved as part of Unicode 9.0 in 2016 and added to Emoji 3.0 in 2016.
The origin of the gesture traces back to the biblical Kingdom of Israel. Courts of Mosaic law would often render verdicts with the phrase "May God have mercy upon your soul" to reaffirm God's supreme authority over the law. Most judges felt that while they could pass a sentence of death upon a person, they personally did not have the authority to destroy souls and that only God had the authority to do that. As a result, some judges would cross their fingers whenever they said the phrase as a result of concern for the criminal's soul as they said it as a prayer.
Common usage of the gesture traces back to the early centuries of the Christian Church, and likely earlier. Christians who would cross their fingers to invoke the power associated with Christ's cross, i.e. blessing. In 16th-century England, people cross fingers or make the sign of the cross to ward off evil, as well as when people coughed or sneezed.
The 1787 A Provincial Glossary, with a Collection of Local Proverbs, and Popular Superstitions by Francis Grose records the recommendation to keep one's fingers crossed until one sees a dog to avert the bad luck attracted by walking under a ladder.
In German-speaking countries and also Sweden the gesture is a sign of lying. Wishing for luck is gestured by pressing thumbs. The same gesture is used in many Slavic countries such as Poland, the Czech Republic, Slovakia, Bulgaria and ex-Yugoslav republics. In South Africa, Afrikaans speakers also have the related phrase "duim vashou" meaning "holding thumbs tightly".

"In early Christian days, a believer confronted by evil or hostile influences implored the power of the Holy Cross for protection by twisting his middle finger over his forefinger and holding the remaining fingers down with his thumb."

To a child, forget ethics. Crossing your fingers while making a promise truly invalidated the promise.
